Overload protection with motor-protective
circuit-breakers
The PKZM0/XTPR...BC1 series are 3-phase electromechan-
ical motor-protective circuit-breakers with bimetallic release
for overload monitoring.
The PKZM0/XTPR...BC1 motor-protective circuit-breaker
disconnects all phases from the main circuit when an over-
load occurs. The power flow to the monitored motor is thus
switched off directly.
