PKZ Motor-Protective Circuit Breakers

PKZ Motor-Protective Circuit Breakers

The PKZ motor-protective circuit-breaker from Moeller is synonymous with quality.

Moeller is reintroducing the popular pushbutton actuation in addition to the rotary drive with the new xStart product system for the PKZM 01 (up to 16 A). Furthermore, the PKZ motor-protective circuit-breaker has been modified and its technical performance improved.

Just as certain as the clear indication of the switch positions in the PKZ series is the secure handling of short-circuit currents: The PKZM 0 and PKZM 4 devices master currents up to 150 kA.
