Motor-protective circuit-breaker
PKZM01, PKZM0 and PKZM4
 
The Compact Starter
It consists of the motor-protective circuit-breaker PKZM0 and the contact module SE00-...-PKZ0 which can be attached and features identical contours. It has been developed for standard applications such as switching and protection of a cooling water pump or a similar application, and complies to the latest motor starter standards:
  • IEC/EN 60 947-4-1

    Whereas the motor-protective circuit-breaker PKZM0 guarantees the disconnection, short-circuit and overload protection tasks, the contact module (contactor) S(E)00-...-PKZ0 assumes the operational switching of the motor current. The compact starter can master a short-circuit current of 100 kA at 4 kW and 400 V.

    While the compact starter represents an economic solution for standard tasks, the high-capacity compact starter was developed specifically for switching and protection of motors in critical processes. This refers to motors whose failure would involve severe consequential costs. In order to guarantee the highest possible level of system availability, the high-capacity compact starter is comprised of the motor-protective circuit-breaker PKZM0 and the weld-free high-capacity contact module (contactor) S00-...-PKZ0. It is guaranteed to be capable of immediate switch on even after a short-circuit of up to 100 kA/400 V.

    The compact starters and high-capacity compact starters from the PKZ2 are available for motor ratings of more than 4 kW/400 V (up to 18.5 kW/400 V, or the combination of PKZM4 with the proven contactor DIL.
