the rated motor current must be set with the setting dial on
the PKE (
The setting dial on the trip block has 16 discrete positions for
the following settings:

Test
The motor-protective circuit-breaker features a test function
(
When the test function is operated with the motor-protective
circuit-breaker switched on, the PKE trips and all main
contacts open. The lines downstream of the PKE can then be
tested for zero voltage. To allow the powered-on motor-
protective circuit-breaker PKE to trip in its test position, a
current corresponding at least with the minimum set value of
the trip block must flow.
