Current ranges of the PKZM0 motor-protective
circuit-breaker
The rated motor current is set on the PKZM0 units by means
of a current dial a (a Fig. 1, Page 24).
15 different types are available for monitoring motors with a
rated current from 0.1 to 32 A (a Table 1).

Temperature compensation
Two parameters influence the deflection of the bimetallic
releases. There is for one the heat which is generated in
proportion to the current flow, and secondly, the influence of
