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.

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.

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.

EZ Ways to Select Schneider Pushbuttons

Emergency stops. Restarts. Line changes. These and other functions have at least one thing in common: pushbuttons.

Pushbuttons are relatively simple devices. At their most basic, the literal push-a-button to facilitate change, they open and close circuits. They can start an industrial process, stop it, or perform other predetermined functions that humans, interacting with machines, deem necessary.

Schneider's new 30 mm pushbutton is at the forefront of the industry.
Schneider’s new 30 mm pushbutton is at the forefront of the industry.

While simple, they are not simplistic. First, there are literal pushbuttons such as the 30 mm from Schneider (pictured), and then there are sibling products in the pushbutton family such as pilot lights and selector switches.

Then there are the many options available. Many, many options in some cases.

To help its customers, Schneider Electric and Steiner Electric have combined to make things a little easier with new pushbutton selector tools.

At the Forefront of Pushbuttons

First, what are all these options?

Today’s pushbuttons are modular in nature and can be augmented with application-specific accessories that can turn them into aesthetically pleasing, easy-to-use human-machine interface (HMI) components. They can be used in a galaxy of applications from pristine production to harsh process environments and integrated into stand-alone machinery or sophisticated, multi-purpose assembly lines … just about any industry with operations that have been automated, but still require some human intervention is an appropriate use.

Schneider Electric is a leader in pushbuttons, including the Harmony line which is distributed by Steiner Electric. The pushbuttons and signaling devices come in a range of styles that provide easy and reliable operations for industrial applications.

In this Schneider video, Jim Clark, Marketing Director Control and Signaling, says that Harmony offers the best-in-class pushbuttons, pilot lights, and switches on the market.

Harmony pushbuttons, which comply with all international standards, have been designed for OEMs, system integrators, panel builders, and others that build, repair, or customize machinery. For them, Schneider offers a unique and unrivaled depth of push-buttons, pilot lights and switches on the market, Clark says.

Visitors to the EZ Selectors page can create a semi-custom pushbutton designed for their specific application.
Various components and accessories for the Harmony 9001K 30 mm pushbutton.

One of the newest products, and an industry game changer, is the 30 mm Harmony pushbutton that expands on its 22-mm version. The 9001 30mm products include pushbuttons, pilot lights, selector switches, and mushroom head buttons. The rugged 9001 operators can feature chrome-plate bezels, black plastic bezels for corrosion-resistant applications, chrome-plated square bezels that provide multi-function operation, and many, many other options. Contacts, profiles, and additional options can be swapped out for something more appropriate.

So how is selection simpler?
