After a trip, an electric motor that has become excessively
hot due to an overload must first cool down. The motor may
not be switched back on until after this.
In order to ensure that this condition is met, PKE motor-
protective circuit-breakers come with a thermal memory
mechanism implemented in their trip block.
A cool condition will be reached after 20 minutes at the
h
latest.
