Why Choose the ABB AUX-C 1Q+1SY 250V AC/DC XT5 W Auxiliary Contact?
The ABB 1SDA104789R1 AUX-C 1Q+1SY 250V AC/DC XT5 W is a cabled auxiliary contact accessory designed for ABB SACE Tmax XT5 withdrawable moulded-case circuit breakers. It combines one changeover contact for circuit breaker open/closed position signalling with one changeover contact for trip indication, enabling reliable status feedback to control, monitoring and signalling systems.
As part of the ABB SACE Tmax XT electrical accessory range, the 1SDA104789R1 is specifically configured for withdrawable XT5 circuit breakers. Its dual auxiliary contact arrangement allows external equipment to monitor both the normal operating position of the breaker and whether a trip operation has occurred.
The auxiliary contacts are intended for signalling circuits below 250 V AC/DC, and the accessory is supplied cabled for integration with the withdrawable circuit breaker arrangement. This makes it suitable for switchboards, distribution panels and industrial installations requiring dependable remote breaker status and trip indication.

Reliable Circuit Breaker Status and Trip Signalling
Auxiliary contacts provide electrical feedback about a circuit breaker's operating state without forming part of the main power path. In the ABB 1SDA104789R1, the Q contact provides open/closed position indication, while the SY contact provides separate indication when the circuit breaker has operated because of a trip condition.
Combining these functions in one cabled accessory simplifies the integration of an ABB Tmax XT5 withdrawable circuit breaker with switchboard indicators, alarm systems, PLC inputs and other monitoring equipment. Its suitability for signalling circuits below 250 V AC/DC provides flexibility across a broad range of industrial control applications.
Typical Applications
- ABB SACE Tmax XT5 withdrawable circuit breaker installations.
- Remote circuit breaker open/closed position indication.
- Circuit breaker trip alarm and signalling circuits.
- Industrial low-voltage switchboards.
- Electrical distribution and control panels.
- PLC, BMS and industrial automation monitoring systems.
