Magnetic Motor Circuit Breakers View all products

The proven 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 PKZM 4 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.

Regardless of whether it is an integrated auxiliary contact, trip-indicating auxiliary contact, voltage release or door coupling rotary handle, the accessories can be used for both the PKZM0 and the PKZM4.

  • All setting ranges are short-circuit proof up to 50 kA (400V)
    - Short-circuit calculations and prefusing are not necessary
  • Common and comprehensive accessories for all sizes
    - Facilitates savings in logistics and engineering
  • Accessories (auxiliary contacts and shunt trips) are installed without tools
    - Reduces installation time
  • Electrically and mechanically compatible to the contactor series DIL
    -Same width for same performance, space-saving installation and transparent engineering
  • All conventional international approvals
    - Common engineering basis for different applications and export countries.
