The Phoenix Contact ECP-E 4A electronic device circuit breaker provides reliable overcurrent protection in a compact 12.5mm wide design. It's ideal for applications requiring space-saving circuit protection, such as industrial control panels and automation systems. The integrated multi-color LED clearly indicates the device's operating or error state, and the status output allows for remote monitoring and integration into control systems. It is designed to be plugged onto TMCP SOCKET M base elements and offers a failsafe element with no required backup fuse.
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.
