The Phoenix Contact ECP 1-2 is a sophisticated electronic device circuit breaker ideal for protecting 24V DC load circuits in applications such as switched-mode power supply units. Its compact 12.5mm design minimizes space requirements, while the integrated LED provides clear visual indication of the device's operating or error state. The inclusion of signal contacts allows for remote monitoring and integration into larger control systems. The ECP 1-2 combines active electronic current limitation with proven circuit breaker technology, offering electrical isolation and limiting residual current to 1.8 times the nominal current. It's suitable for applications requiring selective protection and reliable performance.
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). Parallel connection of multiple load outputs is not permitted.
