PKZM0 switches motors from 0.16 to 32 A. The short-circuit breaking capacity is now rated to 150 kA up to 12 A and 50 kA up to 32 A. The PKZM4 16-63A also has a breaking capacity up to 50 kA. With this, current limiters become almost unnecessary. These motor-protective circuit-breakers are matched to the DIL contactor series, which is ideal for the configuration of motor-starter combinations.
accessories include Integrated auxiliary contact, trip-indicating auxiliary contact, voltage release or door coupling rotary handle, these accessories can be used for both the PKZM0 and the PKZM4.
