Reliable Breaker Status Feedback for Automation Systems
Auxiliary contacts allow the mechanical operating state of a circuit breaker to be represented electrically in an external control circuit. When the breaker changes operating state, the associated auxiliary contacts provide corresponding signals that can be used by indication devices, control relays, PLCs or supervisory systems.
The 24 V DC configuration of the ABB 1SDA073754R1 is particularly suited to modern industrial automation systems that use low-voltage DC control signals. Its four auxiliary contacts provide multiple signalling channels for integrating compatible Emax 2 E2.2, E4.2 and E6.2 breakers into switchboard monitoring and control schemes.
