Motor-protective Circuit-breakers – PKZM0 and PKZM4.

Only two motor-protective circuit-breakers up to 65A

The tried and tested PKZM0 now switches motors up to 32A, and at the same time, its short-circuit switching capacity has been significantly increased. The short-circuit rating (400V) is now 150kA up to 12A and 50kA up to 32A.
The PKZM4 also has a switching capacity of 50kA and is now rated up to 65A, which simplifies engineering and makes current limiters virtually obsolete.

With just two variants, covering the range from 0.1 to 65A selection and engineering are made easy. The PKZM4 with a compact width of only 55mm saves valuable space in the control panel.

Accessories: Full functionality with only few versions
Both breakers use the same simple clip-on accessories, which can be fitted without tools, making selection easy and greatly reducing stock handling.
The auxiliary contact modules provide failsafe information about the switching state; On or Off; overload or short-circuit.
Other accessories include trip-indicating contact, voltage releases and door coupling handles.
