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.
