About Relays

These relays combine solid state and mechanical operation to provide long service life without the need for a heat sink. Use with resistive heating loads; relays cannot be used with motor loads. An LED indicator tells you if the relay is open or closed.

Note: Relays cannot be used with an RC snubber.

High-Current Relays

3 Circuits

4 Circuits

Use these relays with large motors and lighting systems. Also known as IEC contactors, they are built to International Electrotechnical Commission (IEC) dimensional standards. All have recessed terminals to prevent contact with live connections. Mount to 35 mm DIN rail.

Auxiliary contacts allow you to add a signaling device or control another relay. Add one front-mount contact per relay or two side-mount contacts per relay.

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.

Infrequent-Cycle High-Current Relays

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 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.
