Unit description
Overload protection with motor-protective circuit-
breakers
The PKZM0 series are 3-phase electromechanical motor-
protective circuit-breakers with bimetallic release for
overload monitoring.
The PKZM0 disconnects all phases from the mains circuit
when an overload occurs. The current flow to the monitored
motor is thus switched off directly.
