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.

For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Connections are accessible from the front, so you can mount relays side-by-side. Also known as definite-purpose contactors.

Enclosures (sold separately) are NEMA 1 rated to protect contacts from corrosion.

Also Available: Auxiliary contacts for 3.8"-7.2" Ht. relays. They allow you to add a signaling device or control another relay. Please select 6564K99, then select the McMaster-Carr part number of your relay and whether you want to switch one circuit on (1 Normally Open) or off (1 Normally Closed).

DIN-Rail Mount Infrequent-Cycle High-Current Relays

Mount these relays directly to 35 mm DIN rail. For use with equipment that cycles on and off, they meet UL 508 for air conditioning and heating. All have recessed terminals to prevent contact with live connections. Also known as definite-purpose contactors.

Auxiliary contacts allow you to add a signaling device or control another relay.
