“Latching Shutdown on Thermal Overload” Mode [
5)
The circuit breaker can be used for activation during installation. In this case, the circuit breaker must meet
all the requirements on this shutdown device. If an additional switch is used, it must have the same electrical
load capacity as the circuit breaker.
