CB E1 24DC/4A NO P - Electronic circuit breaker

Electronic circuit breaker, 1-pos., active current limitation, 1 N/O contact, plug for base element.

This product needs further products for operation. Mandatory Accessories

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.
