Overload protection with motor-protective
circuit-breakers
The PKZM4/XTPR...DC1 series are 3 pole electromechanical
motor-protective circuit-breakers with bimetallic release for
overload monitoring.
The PKZM4/XTPR...DC1 switch disconnects all phases from
the mains circuit when an overload occurs. The current flow
to the monitored motor is thus switched off directly.
