EC-E1 12A - Electronic circuit breaker

0903031

Electronic circuit breaker, signal contact: 1 N/O contact, nominal current: 12 A

General 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.
