PKZM 0 and PKZM 4 – Only Two Circuit-Breakers up to 65 A

The tried and tested PKZM 0 now switches motors up to 32 A. Simultaneously, its short-circuit switching capacity has been increased significantly. The short-circuit rating (400 V) is now rated to 150 kA up to 12 A and 50 kA up to 32 A.

The PKZM 4 also has a switching capacity up to 50 kA. It facilitates engineering. Current limiters become practically obsolete.

With just two motor protection variants, the entire range from 0.1 to 65 A is covered. It saves precious inventory space and simplifies the engineering effort.

The PKZM 4 with a width of just 55 mm is the narrowest switch for 65 A. Precious space in the control panel is saved!

Accessories: Full functionality with only few versions

The auxiliary contact modules can be fitted without any tools and provide fail-safe information about each switching state. This also applies to the NHI-E auxiliary contact module, which fits within the PKZ and can be mounted from the front. Additional advantage: It is within the unit width and thus requires no space at the side.

Whether it be an integrated auxiliary contact, a trip-indicating auxiliary contact, a voltage release or door coupling handles, the accessories for the PKZM 0 can also be used for the PKZM 4.
