About Relays

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.

High-Current Relays

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 Medium-Current Relays

1 Circuit, 55 Amp

Mount these relays directly to 35 mm DIN rail. They are solid state, so they have no moving parts and have an extended service life. Relays have an attached heat sink that disperses heat to provide optimal convection cooling.
