Motor Protective Circuit Breakers

Machinery and installation downtimes should be kept as short as possible. The PKZ fuseless motor-protective circuit-breakers combine short-circuit and overload protection in one device, allowing fast restart readiness. The PKE line of motor-protective circuit breakers with electronic wide-range overload protection provides highest level of flexibility featuring a compact and modular design with plug-in control unit for motor currents up to 65A, which makes it an interesting alternative to the bimetal solution and complement the PKZ family. PKZM01, PKZM0, PKZM4 and PKE have the same accessories, and can be combined easily with DILM contactors and DS7 soft starters.
