Why Choose the ABB 1SDA123476R1 AUX 6Q 24 V Auxiliary Contact?
The ABB 1SDA123476R1 is an AUX 6Q auxiliary contact assembly designed for fixed ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers. Featuring six changeover auxiliary contacts with a 24 V contact rating, it provides electrical indication of the circuit breaker's open or closed position for integration into control, signalling and monitoring circuits.
Auxiliary contacts allow the mechanical state of an Emax 2 breaker to be communicated to external equipment. The six Q contacts in the 1SDA123476R1 provide multiple independent signalling paths, making the assembly suitable for applications where breaker status needs to be supplied simultaneously to control systems, indication circuits, interlocking logic or supervisory equipment.
The suffix F identifies this version for fixed Emax 2 circuit breakers. ABB specifies the accessory for the E2.2 through E6.2 frame sizes, providing a dedicated solution for expanding the electrical status-signalling capability of compatible fixed breakers.
