Why Choose the ABB AUX-SC S33 M/2 250V AC/DC XT7M 1SDA104825R1?
The ABB 1SDA104825R1 is a genuine spring-charged status auxiliary contact for ABB SACE Tmax XT7M circuit breakers. Identified by ABB as AUX-SC S33 M/2 250V AC/DC XT7M, this accessory provides an electrical signal indicating the charged condition of the operating mechanism springs.
The accessory incorporates one SPDT changeover contact and is designed for signalling circuits operating below 250 V AC/DC. The S33 function enables the spring-charge condition of the XT7M operating mechanism to be communicated to external indication, control or monitoring equipment.
Designed specifically for the ABB SACE Tmax XT7M, the 1SDA104825R1 uses a spring-clamp electrical connection and is suitable for configurable circuit breaker installations. It complies with IEC 60947-2, is listed within ABB documentation for UL applications and provides a compact manufacturer-engineered solution for remote mechanism-status signalling.

Spring-Charged Status Signalling for ABB XT7M Circuit Breakers
Stored-energy operating mechanisms use charged springs to provide the energy required for circuit breaker operation. Monitoring the spring-charge condition allows operators and control systems to determine whether the mechanism is in the appropriate state for subsequent operation without requiring direct visual inspection of the circuit breaker.
The ABB 1SDA104825R1 provides this information through its S33 changeover contact. The spring-charged signal can be incorporated into switchboard indication circuits, PLC inputs, remote monitoring systems and automation logic, making the accessory particularly useful where the operating status of an XT7M circuit breaker needs to be supervised remotely.
Typical Applications
- Spring-charged status indication for ABB SACE Tmax XT7M circuit breakers.
- Remote circuit breaker mechanism monitoring.
- PLC and industrial automation input circuits.
- Low-voltage switchboard indication and control systems.
- Building management and electrical supervision systems.
- Industrial and commercial power distribution installations.
