Get Modified Enclosures Without the Hassle

Get Modified Enclosures Without The Hassle

Are your highest paid, best-trained employees spending their time measuring and marking up, drilling and cutting your enclosures? Has modifying those enclosures to meet exacting customer specs become a production bottleneck? Do design revisions during the build cycle cause documentation headaches?

If you answered yes to any of these or similar questions, I have one more question for you. Why are you still manually modifying enclosures in house?

Don’t waste time making holes and cutouts manually–let Steiner Electric, the exclusive Hoffman Certified Modification Center in Northern IL, deliver your modified enclosures and back panels to you, on your schedule and ready to populate so you can focus on integrating and providing control solutions to your customers.

Get modified enclosures fast

For contractors that produce electrical and electronic assemblies for end users, modifying enclosures is essential to the panel building process, but the task does not bring the most value-add to a project.

Steiner’s CNC-based Hoffman Certified Modification Center, the ModCenter 293, eliminates the time-consuming and costly manual methods of modifying enclosures. The automated system makes your shop more competitive, efficient, improves your bottom line and can make design changes on the fly.

Reduce your lead times by modifying stocked or quick-ship enclosures and have them delivered to your facility or job site on your schedule. In addition, the quality of the cutouts are higher and turnaround times on custom enclosures and back panels are faster.

Utilizing an automatic tool changer, the machine can use any of 21 precision cutters — a combination of drills and taps for holes and end mills for cutouts. The ModCenter can mill mild steel at 2,000 mm (78 in.) per minute, and it can make a 4- by 4-in. in under 3 minutes. Including filing and cleanup, it can take a person about 15 minutes to manually do that job.

Get precise cutouts and custom enclosures fast with the ModCenter 293.

Considering that a 36-in. by 48-in. electrical enclosure could have 40 to 50 holes and cutouts and a back panel could have as many as 200 holes with taps, the ability to accurately and expeditiously customize enclosures is vital.

Dan Williams, manager of the Steiner Electric Custom Products Group says, “By automating labor-intensive modification tasks we can increase productivity, quality, and flexibility. We can produce holes and cutouts in minutes, not hours, and when we are done the holes are precise and clean and ready to populate.”

From small to large enclosures

The CNC unit handles enclosures up to 93.7 in. by 86 in. and back panels up to 93 in. by 94 in. It can process a variety of materials including mild steel, stainless steel, aluminum, copper, PVC, and glass-reinforced plastic (GRP).

Automatic tool changer that holds up to 21 tools.
The tool changer holds 21 tools.

Vertically oriented and operating in multi-axes, the unit grabs a tool and makes all the cuts that it can with that cutting tool, moving along a preprogrammed cutting path, before exchanging the cutter with another tool to continue the process.   The CNC machine operates along these vertical lines, explains Williams. “It rides on this plane, modifying whatever is on the plane.”

A flexible machine, the ModCenter 293 allows for fast changes if needed.  “We are like an on-site job shop,” says Williams.  “Our number one priority is to make sure our customers get the enclosure they need for the job, at a competitive price, and get it on time, every time.”

The ModCenter 293 features software that integrates seamlessly with CAD DXF, DWG, and other file formats to push jobs forward. This saves workers from the laborious job of copying a pattern by hand.

Having Steiner do the modification work may also reduce tooling costs. Drilling holes and making cutouts by hand is hard on tooling. Depending on the enclosure material, drill bits can wear out after about 150 holes. Saw blades, especially when cutting stainless steel, can wear out in just minutes.

With benefits such as precision cutting, fast turnaround times, and labor-savings, outsourcing your enclosure modifications to Steiner can be a good decision in many ways.

Protect Your Motor with Manual Starters and Switches

Schneider Electric manual starters and switches are compact and elegantly designed devices that are primarily used to switch motors ON/OFF. Despite their simplicity, they can reverse the motor depending on the model and protect the motor against overloads, shorts, and phase failures in fuse-less applications. These devices, which are typically operated by toggle or push button, come in a variety of options from reversing and non-reversing to multi-speed choices.

Schneider manual starters and switches come in a variety of options to suit your specific application.

Steiner stocks a large inventory of manual motor starters and switches for pickup at one of our convenient locations or on-time delivery to your facility or job site, including fractional horsepower manual starters with melting alloy overload relays; manual switches that are horsepower rated for self-protected motors; and manual starters with integral horsepower with melting alloy overload relays.

It is now easier to configure the right motor starter and switch for your application by using the Schneider EZ Selector. When it comes to manual starters and switches, the EZ Selectors make it especially easy to choose from various versions and multiple options of (type F) fractional starters, (type K) manual switches, and (type M, T) starters with melting alloy overload relays.

Application Considerations

Manual starters are designed for low horsepower motor applications. In fact, many small motors use a fraction of a horsepower to run, and Schneider offers manual starters designed specially for these fractional horsepower motors.

The starters are especially suited for being mounted directly onto or near the machine that is controls. They can be used as stop-starts without the need to run extra power cords and wires.

The starters can be chosen based on the type of electronic to be controlled and protected. Is the application a single-phase or three-phase? What is the full-load amperage? Does your application require 1 or 2 pole configurations or 2 or 3 pole configurations?

The environment in which they are to operate is also a primary concern. Some starters must be dust proof or be oil resistant. If a dusty environment, the starter might require a NEMA 12 enclosure that will protect against dust, dirt, and dripping non-corrosive liquids, oil and lubricants. A NEMA 4 enclosure is often intended for outdoor use where extra protection against moisture and wind driven rain is required.

Some models are available in specific NEMA enclosures. Type F fraction HP starters are available in NEMA Type 1 enclosures (oversized and flush-mount enclosure option available), Type 4 enclosures (with zinc alloy die casting), and NEMA Type 3R, 7 and 9 (cast aluminum enclosure).

Various models also have specific operators. For instance, for Type M and T integral horsepower starters, a push button or toggle operator is available in open and NEMA Type 1 enclosure, while a direct acting push button is only available on NEMA Types 4 and 12 enclosures.

Thermal overload is also a consideration to protect a motor against overheating.  For example, the ambient temperature of a cabinet with multiple electronics could become so hot that nuisance tripping occurs.

To solve these problems, many switches, such as the Type M and Type T units, feature melting alloy thermal units. Depending on the thermal load, these starters might necessitate their thermal overload protection adjusted for the heat (See video below). The thermal overload protection developed by Square D has a special alloy in it. When the ambient temperature reaches a certain level, the protective relay undergoes a phase change from solid to liquid and shuts off the motor. This greatly reduces the chance of motor damage.

These considerations are just a few options that must be taken into account when choosing the correct manual starter or switch for the particular application.

Hoffman Thermal Audits Provide Solutions to Cool Electronics and Maximize Equipment Life

Hoffman thermal audit maximizes equipment life

Summer’s coming, and the time to begin protecting your electronics, before it’s too late, is today. As temperatures rise, industrial electronics can overheat, causing malfunction and even complete device failure. In fact, statistics show that for every 18°F over room temperature, the life expectancy of an electronic device drops by 50%.

To determine thermal heat loads, and examine the stress placed on electrical devices by excess heat, Steiner is offering a FREE THERMAL AUDIT to be conducted by its Hoffman-trained and certified expert.

A thermal audit can identify problem areas and produce compelling evidence of excess heat that can affect performance and potentially damage critical equipment.

Are Your Electronics in Danger?

Keeping electronics cool is essential to maximizing the life cycle of electronic devices, reducing mean time between failures (MTBF), cutting capital expenses, and keeping production humming along.

Heat is generated internally by electronic components and intensified by external sources. Inside a cabinet, uncooled components can generate as much trapped heat as a home furnace.

Heat sources include:

  • AC power supplies
  • Controllers, drives and servos
  • Transformers and rectifiers
  • Processors and server racks
  • Radio equipment
Thermal energy from an electrical enclosure is measured during a thermal audit.

To cool the electronic and its components, the thermal energy must be transferred away from the device. There are a few basic ways to cool industrial enclosures, including using a sealed enclosure that utilizes a heat exchanger, an A/C unit that uses a fan to circulate fresh air through a cabinet, or via conductive cooling in which the heat radiates through the cabinet.

Without these measures, temperature variations can lead to everything from nuisance problems to shutdowns. Tripping can become a source of frustration, and heat stress can affect loop controllers, PLCs and more.

At high temperatures, drive performance can be derated, and I/C-based devices can behave strangely creating unusual output such as voltage fluctuation. At low temperatures, cooling below the dew point can lead to condensation and promote corrosion.

For instance, MOSFET transistors, which are voltage-controlled field effect transistors made from metal oxide and silicon components, can falter from excess heat. High temperatures can change the properties of the silicon oxide. The higher the temperature, the higher the threshold voltage that triggers an open gate. At too high of a temperature, the gate may not open at all.

Another potential heat-related hazard pertains to wiring insulation. With increasing temperatures, elasticity and strength of the insulation are reduced, and ductility can temporarily increase.

What is Tested During an Audit

When a facility is audited, the inspector looks at all the factors that could affect temperature increase. Typically, a Hoffman thermal audit examines:

  • Heat load of enclosed electrical equipment
  • Temperature ratings of the installed equipment (upper and lower limits)
  • Ambient temperature (typical and extreme)
  • Environmental conditions
    – Clean air (Type 1)
    – Dirty or wet environment (Type 12, Type 4/4X)
    – Closed- or open-loop cooling systems
    – Indoor or outdoor enclosure location
  • Maintenance and frequency of access requirements

When finished, a report is developed that will provide recommended thermal management solutions. These best practices are designed to keep electronic components cool and help minimize unplanned failures.

A thermal audit helps determine best practices for managing thermal energy.
A thermal audit helps determine best practices for managing thermal energy. Free Hoffman Thermal Audits are available from Steiner Electric.

Essentially, by removing the waste heat, efficiency can be increased while downtime and operating costs are reduced.

Allowing electronic components to run hot can be a gamble that could require a company to prematurely replace industrial drives, cause hours of automation system downtime, and create out-of-warranty conditions when cooling is not used.

Schneider Electric Provides Safety Switches For Infinite Applications

Schneider’s Square D Safety switches are vital components to safety and power control. They are a means to disconnect from the electrical load and provide protection to the branch circuit.

When necessary, they can be used to disconnect manufacturing equipment, heavy machinery and light commercial and residential applications from its power source. Users may need to disconnect equipment from its electrical supply for a variety of reasons from scheduled preventive maintenance to emergency stoppage.

The performance of safety switches is important to the safe operation of many industrial applications. In addition, requirements from a variety of organizations  have increased the use of safety switches in many commercial and industrial facilities.

In addition, safety switches are an NEC requirement in industrial and manufacturing facilities.  For instance, a safety switch must be in sight from all motors or manufacturing equipment and not more than 50 feet from the equipment it controls.

A key performance benefit of the Schneider safety switch is its ability to break load. A locked motor can draw six to eight times motor full-load current. In an emergency situation, it’s important to have a safety switch with enhanced load-break features such as those featured in Schneider’s switches. A key element of Square D safety switches is its blade and jaw construction that has been designed to manage heavy motor loads and arc interruptions.

Multiple types of disconnect switches are available, and the switch that work for you depends on a number of factors in your working environment.  Steiner’s expertise can help make the appropriate choice. Steiner stocks a large inventory of safety switches ready for pickup at one of our convenient locations or on-time delivery to your facility or job site, including: general duty, heavy duty and double throw switches in single and multiple pole, fusible and non-fusible.

Here is a look at some of the most common safety switches.

General Duty Safety Switch
Schneider Electric Square D General Duty Safety Switch

One of the most go-to safety switches are those that are considered General Duty (GD) safety switches. These are designed for residential and commercial applications and where durability and economy are prime considerations. Typical loads are lighting, air conditioning, and appliances. They are suitable for use as service equipment when equipped with a factory or field-installed neutral assembly or a field-installed service grounding kit as applicable.

  • Voltage: Maximum voltage of 240 V
  • Current Rating: Max amperage of 800 A
  • Enclosure: Available in Type 1 and Type 3R enclosures
  • Certification: UL Listed, File E2875
  • Standard: Meets or exceeds the NEMA Standard KS1

Double Throw Safety Switch

Double throw safety switches are designed for manual transfer of one load between two power sources. The units are tough and reliable to provide emergency back-up power connections in accordance with Article 702 of the National Electrical Code, ANSI/NFPA 70.

  • Voltage: Maximum voltage of 600 V (ac/dc)
  • Current Rating: Max amperage of 600 A
  • Enclosure: Available in Type 1, Type 3R, Type 4, Type 4X, Type 5 and Type 12 enclosures
Make Selections EZ

These safety-switch options, and others that are more specific in application, come with multiple options such as various difference in amperage and voltage. In some cases, the question is whether to use fusible or non-fusible switches.  Fusible safety switches combine fuses with the switch in a single enclosure. For both fusible and non-fusible safety switches, when the circuit is open, the safety switch disconnects the load from its source of power, while closing the circuit reconnects the load.

Lutron Vive Commercial Lighting Control Solution is Easy to Install and Simple to Manage

Every year, thousands of buildings are built or retrofitted. Every one of these spaces can benefit from lighting control that saves energy, improves comfort, and enhances productivity.

Vive from Lutron is a simple, flexible and scalable lighting control solution that can help the facility manager, owner, tenant, contractor, maintenance personnel and other personnel to reap these benefits. The system is comprised of a full family of wireless devices that can be tied together to enable centralized control, monitoring and system integration.

From conference rooms to entire buildings, Lutron Vive gives users complete lighting control.
From conference rooms to entire buildings, Lutron Vive gives users complete lighting control.

Vive can help buildings meet stringent energy codes, improve building performance, and do so on budget and on schedule. Wireless controls allow you to design options that provide the right functionality for each space in your building.

Vive is simple enough to deliver basic energy savings and robust enough to apply additional lighting control strategies such as time-clock scheduling, energy and system monitoring, demand response, load shed, and seamless integration to BMS via BACNet with software that works on any smart device.

Vive lets you combine lighting control strategies to maximize efficiency such as occupancy/vacancy sensing, daylight harvesting, scheduling, demand response, plug load control, high-end trim, personal dimming control and even HVAC integration.

Vive is a wireless, scalable product. Not have to hardwire each device makes for faster and less expensive installation costs.
Vive is a wireless, scalable product. Not having to hardwire each device makes for faster and less expensive installation costs.

When launching the brand in 2016, Eric Lind, vice president of global specifications, said, “To a building owner or facility manager, Vive represents a scalable, flexible lighting control solution that easily transforms a building one step at a time, or as space needs change, and helps address energy-saving issues. To contractors, Vive represents a reliable, simple, time-saving product that’s versatile enough to control all light sources in any size commercial building. This product addresses the needs of customers on many levels.”

Built around a wireless hub, the Vive system allows you to add components and control as needed.
Built around a wireless hub, the Vive system allows you to add components and control as needed.

Traditional installations can be labor intensive and complex to set up.

Vive, on the other hand, is simple. Wireless control can be installed as much as 70 percent faster than traditional wired lighting controlled solutions. This reduces labor costs and minimizes disruption among workers and those utilizing the space.

In addition, Vive helps meet lighting control code requirements for new construction and retrofits such as for ASHRAE 2010, ASHRE 2013, IECC 2022, IECC 2015, and Title 24-2016.

Wireless installs

Lutron utilizes its Clear Connect® Wireless technology to establish communications with lighting and building controls at a range of 71 ft (22M).

Clear Connect operates on the 435 MHz band wave, while many other wireless technologies operate on the more traditional 2.4 gigahertz band wave. This 2.4 GHz band wave is much more frequently used, and this congestion could create problems that could cause a failure–which might be okay when streaming a movie, but lighting a commercial building is another story.

Lutron chose 435 MHZ band wave because it is less busy; in fact, the FCC puts limitations on the amount of traffic that can operate over this wavelength. The limit makes it a much quieter band, and so the messages are able to get through more reliably.

For the actual installation process, Vive offers wallbox mounting, ceiling mounts, and Vive-enabled fixtures on a standard junction box.

Wallbox mounting allows contractors to replace an existing switch in a standard wallbox to control a group of lights, and it requires no new wiring. For the ceiling mount, PowPak modules mount on a standard junction box in the ceiling to control groups of lights. It saves installation time by eliminating wiring down through walls. Vive-enabled fixtures have wireless control and sensing built into the fixture. No additional wiring is required.

For example, if a contractor or MRO is replacing a switch in a restroom where there is currently a toggle switch on the wall, the installer takes out that toggle switch and puts in either a wireless switch or a dimmer into that location without any new wiring. Simply commission the switch by holding the remote’s button down for several seconds.

Vive is also easy to commission, which is a good thing if the installer and the person starting to use the controls are not one in the same. The person doesn’t have to climb on a ladder to find the load controllers, the Pico remote controllers can find nearby devices based on RF signal strength. Simply holding the button down for a few seconds does the trick.

XCT Sensing Technology

Another strength of the system is its sensing technology. Standard PIR sensors are good at detecting major motion like a person walking; however, they have difficulty detecting less obvious movements.

That is where the Lutron XCT technology comes into play. This “Cross Correlation Technology,” as the company calls it, can take measurements utilizing passive infrared sensors and sophisticated algorithms to distinguish the difference between background noise and actual motion. By fine tuning these waves, the sensor can go beyond simple major movement such as someone pacing the floor, to notice when someone is doing more passive actions such as working at a desk or reading a report and keep the lamps lit.

So, Vive can control that one office fixture or it can also be tied into building management systems. A simple ethernet port ties Vive to other building systems. The BACnet/IP protocol is the primary means of integration. BACnet is embedded or native in the Vive wireless hub, which means no external interfaces or gateways are required to communicate with other systems.

For instance, Vive can be tied into a buildings’ heating, ventilation and air conditioning system and utilize its occupancy/vacancy sensors to heat and cool individual rooms, floors or whole buildings. While some buildings have already begun integrating HVAC control into their building SOPs, in the future this capability might be required by code.

Getting the right bulb

Want Lighting Incentives? Check New Ground Rules

If you are considering a lighting upgrade or you are bidding on a lighting job for the Standard or the Public Sector that would require ComEd incentives to facilitate, it is imperative that you follow new certification guidelines passed by Illinois legislation. Non-compliance will result in a loss of financial incentives.

The Illinois Commerce Commission (ICC) requires the installing contractor to be certified in order to receive any utility incentives.  According to Steiner Electric’s Lighting Division, contractors must fill out the application, send the appropriate “good standing” business form, an insurance form that has been notarized, and then mail that packet to the Commission. Then, the ICC will review the application.

According to an email from the utility:

“If the end user does not do a self-install, they must have a certified contractor install the material or the they will not qualify for a rebate. The new program goes into place on January 1, 2018, and includes any projects that are given extensions from the 2017 program year … ”

In accordance with the Future Energy Jobs Act, the Illinois Commerce Commission requires a trade ally company, i.e. contractors and home builders, to certify as an Entity Installing Energy Efficiency Measures.

To assist your company in complying with the new guidelines (Section 16-128B of the Public Utilities Act, and 83 Ill. Adm. Code (Part) 462), Com Ed has put the appropriate forms necessary to apply for the certification on its website. The forms can be found at the Illinois Commerce Commission’s Energy Efficiency Measures Installer website: https://www.icc.illinois.gov/Electricity/authorities/EEMI.aspx,

At this website, contractors can find:

  • The 250 A frame has a 35kA @480 V interruption rating, and trip circuits are rated at 150 A, 200 A, 225 A, and 250 A.

Both devices require minimum space because of their compact design. The footprint for the 3VA5 125 A frame model is 3 in. by 3.8 x 5.5 in. and the footprint for the 250 A frame is 4.13 in. x 4.21 x 7.28 in.

Safe Tripping

For safe operation, the 3VA5 Siemens circuit breakers are based on the concept of thermal magnetic trip units (TMTUs). These TMTUs are two separate tripping mechanisms – thermal and magnetic—that are built into the same device.

In a thermal-magnetic circuit breaker, the trip unit includes elements designed to sense the heat resulting from an overload condition and the high current resulting from a short circuit.

The thermal safety component works on thermal inverse-time, meaning the higher the current, the faster the breaker trips. The thermal element is a bimetallic strip, which means it has two different metals bonded together that have different thermal expansion characteristics. As that strip warms up, the thermal differences cause the metals to twist and bend and eventually contact a trip bar causing the contacts to spring open.

The second safety component is the magnetic trip. The circuit breaker has a trip unit that senses a magnetic field generated by current to detect a short circuit. This type of circuit breaker trips immediately when a short circuit occurs, but delays an appropriate amount of time before tripping in the event of an overload.

Array of Design Options

Steiner offers a wide range of Siemens’ internal accessories that can fit in any of the 3VA products. They can be adapted flexibly, quickly and easily to individual specifications. Color coded for simple installation process, they are designed to always be installed at the correct position in the circuit breaker.

Accessories include multiple operator options, including door mounted rotary operators that come either with illumination, which provides a clear indication of the switching position, and without an illuminating kit.

Also available is the Max Flex flange mount operating system that allows the user to locate the circuit breaker almost anywhere within an enclosure. It uses a flexible cable that connects to a breaker operator mechanism and a handle located on the enclosure’s flange.

Also available are auxiliary and alarm switches that can be integrated with all sizes of Siemens breakers. The switches snap for easy installation and to swap out as needs change.

Auxiliary switches can be used to operate indicator lights, relays or other accessories to provide the breaker’s status. Alarm switches indicate that the circuit breaker has tripped due to an overload, short circuit or ground fault. A shunt trip will trip a breaker remotely, and an under voltage trip release will activate when voltage shuts off or dips.

So, when looking to install new or replacement breakers, consider the 3VA5 products that offer myriad design possibilities.

Hubbell Disconnect Switch Enhances Safety with LED Phase Indicators

Hubbell Insight Circuit Lock with LEDs

The National Electronic Code requires that disconnect switches be in the line of sight of a user, motor and the equipment the motor drives. This allows the motor to be shut down for maximum safety. Now, Hubbell Wiring Device-Kellems has upgraded its 30amp disconnect switches to include LED lights that takes this line-of-sight visibility to the next level.

The company has introduced technology, dubbed inSIGHT™, that incorporates six LED phase-indicator lights. Three LEDS show the status of the line side and three lights represent the load side wiring. The electrical status of each phase is within sight and clearly displayed on the cover so that users are provided a secondary way to confirm make/break on all phases prior to removing the enclosure cover. For example, if there is a welded contact or dropped phase the operator can determine that a problem exists (see Fig. 1).

With an ever growing focus on safety improvements, Hubbell disconnects provide a difference you literally can see.

Hubbell phase-indicating disconnect switches are available in non-metallic, and stainless steel square top and sloped top versions. Replacement covers are available for upgrades to existing installations.

The 30A Circuit-Lock Disconnect Switches are available with or without a jog switch to slowly move the motor forward or in reverse. Customers have the option to either purchase the entire disconnect unit or an LED replacement cover for compatible existing 30A Disconnect Switches.

As with most NEC-certified disconnect switches, when locked in the “off” position, the high-visibility red rotary handle complies with OSHA lockout/tagout requirements. When in the “on” position, the cover cannot be opened.

Designed to be tough, reliable and provide exceptional performance in the most grueling conditions, the disconnect switch’s IP69k rating means that it can withstand high-pressure, high-temperature washdowns. The units have been tested to withstand extremely hot water (176degF) and high-pressure water spray (1450psi) from various angles. In other destructive testing, the device is placed in a dust chamber for 8 hours while a vacuum attempts to pull dust into the sealed housing.

The switch is also certified by the NSF for use in food processing applications, and is UL Listed for Type 4X, which means that it can be used for either indoor or outdoor applications. It is also listed for Type 12 enclosures, which are enclosures constructed without knockouts for indoor use to protect personnel against access to hazardous parts, and to provide ingress protection for the electrical contents.

Features:
* Six highly visible integral phase identification LEDs
* External LEDs provide secondary means of visual confirmation of make/break on all phases
* Cover cannot be removed with switch in the “ON” position
* Certified by NSF for hygiene in Food Processing applications
* Highly visible red handle which meets OSHA LO/TO capabilities
* Available in 30 Amp non-metallic and stainless steel versions, with or without JOG switch
* UL witnessed IP69k and UL Type 4X and 12 Environmental ratings
