Comprehensive 24 V Circuit Breaker Status Signalling
Auxiliary contacts translate the mechanical open or closed state of a circuit breaker into electrical signals that can be used by external control and monitoring equipment. These signals can be connected to PLC inputs, indicator circuits, supervisory systems and other automation equipment to provide dependable breaker-state feedback.
With its 15-contact 24 V configuration, the ABB 1SDA073761R1 provides substantial signalling capacity for complex Emax 2 installations. Its compatibility with fixed and withdrawable E2.2 through E6.2 circuit breakers makes it suitable for advanced switchboards where multiple systems require access to breaker-status information.
