Rated IP66, these switches are protected from washdowns. They cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance.

Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).

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.

Also known as automotive relays, these relays can handle high starting (inrush) currents.

Relays for surface mounting have a tab for added security in high-vibration applications.

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).

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.
