The PKE device is a three-pole motor-protective circuit-breaker with
electronic wide-range overload protection designed to monitor electric
motors for overload.
In the event of an overload trip, the PKE will disconnect all poles from the
main circuit using the PKE-XTU(W)(A)-... trip block. This stops the power flow
to the monitored motor directly.
