Phoenix Contact ECP12 Electronic Device Circuit Breaker

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.
