EC-E1 3A - Electronic circuit breaker

0903025

Electronic circuit breaker, signal contact: 1 N/O contact, nominal current: 3 A

Product details

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.
