Infrequent-Cycle High-Current Relays
2 Circuits
3 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 Long-Life High-Current Relays
With no moving parts, these solid state relays have an extended service life. Mount them directly to 35 mm DIN rail. They have an integrated heat sink that disperses heat to provide optimal convection cooling. An LED indicator tells you if they are open or closed. Relays are rated for continuous operating duty. They do not switch DC loads.
