4 Circuits

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.
