Eaton PKE-XTU-4 Electronic Overload Release Unit, 0.3-4 A, 690 V AC, for PKE12/PKE32 121724

In industrial motor control panels, the Eaton PKE-XTU-4 electronic overload release unit protects three-phase motors up to 4 A from overloads. It installs directly into an Eaton PKE12 or PKE32 motor protective circuit breaker, combining short-circuit and overload protection in one compact device. The wide adjustment range from 0.3 A to 4 A allows precise matching to motor full-load current without needing separate overload relays.
