The Phoenix Contact ECP-E 4A electronic device circuit breaker is a compact solution for protecting electronic circuits in industrial applications. Its design width of just 12.5 mm makes it ideal for space-constrained environments. The multi-color LED provides clear indication of the operating or error state, and the integrated status output allows for remote monitoring and control. It can be plugged onto TMCP SOCKET M base and offers features like active current limitation and a required backup fuse element. This circuit breaker is suitable for a wide range of applications, including power distribution and control systems.
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.
