Collection: WEG CWB Overload Relays

The WEG CWB series of overload relays are designed to attach directly below a WEG CWB contactor.  They can also be used on any contactor using the stand-alone accessory.

Overload relays work together with a contactor to protect electric motors from a variety of fault conditions.  To read more about how overloads operate and protect motors, see Overload Relay Protection.
