General
Installation instructions
When mounted in rows without convection cooling, the nominal device
current should only be led to a maximum of 80% due to the thermal
effect during continuous operation (100% operating factor).
Special precautionary measures must be taken in systems or machines,
to prevent components from restarting (e.g., use of a safety PLC).
Parallel connection of multiple circuit breakers is not permitted.
