4 Using the device
Settings Before commissioning the motor-protective circuit-breaker,
the rated motor current must be set with the setting dial on
the PKE (
a table 1, Page 40).
The setting dial on the trip block has 16 discrete positions for
the following settings:
Table 8: Overview of settings on the trip block
Test The motor-protective circuit-breaker features a test function
(
a figure 7, Page 44).
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.

To ensure its safety function, motor-protective circuit-
breaker PKE must be tested with the built-in test function
at least once a year.
