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.

These starters are more compact than electrically actuated motor starters. Use them when multiple motor circuits are housed in one panel. They provide on/off control for a motor and protect it from overloads—starters will shut the motor off if current exceeds the full-load current rating. Set the adjustable overload relay for the exact overload current needed.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).
Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.
