Choosing an Electrical Switch

About Relays

Install these switches in a panel cutout. Small enough to fit in tight spaces, they handle comparable electrical loads to standard sized switches. They cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. All have a lockout so you can secure them in the off position with a padlock (not included). They’re rated IP65 for protection from washdowns.

Enclosure Disconnect Switches

Install these switches inside an enclosure to prevent it from opening when power is on—turn the switch to disconnect power and release the door. Cut the shaft to fit the enclosure. Use a padlock (not included) to lock switches in the off position. Mount to DIN rail inside an enclosure; mounting depth is the distance from the panel door to the DIN rail. UL listed, C-UL listed, and CE marked, these switches meet American, Canadian, and European safety standards.

Use optional sealing gaskets in washdown environments; they create an IP65 rated seal around the actuator.

Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.

Use additional power poles to control more than three circuits. Add neutral poles to open and close the neutral leg of a three phase system.

Add junction blocks to connect a ground wire.

Terminal covers prevent contact with live terminals.
