About Relays

Control equipment with high currents such as air conditioners, heaters, and ventilating equipment. They automatically turn electrical equipment on or off after a set interval of time.

Switches with override can bypass the automatic shut-off.

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.
