£62.74
The ABB 1SDA104811R1 is a genuine auxiliary contact for ABB SACE Tmax XT7 circuit breakers, designed to provide external electrical indication of circuit breaker status. ABB identifies the accessory as AUX 1S52 250V XT7, with one S52 changeover contact for signalling applications.
The S52 contact provides tripped indication, allowing an external monitoring or control circuit to receive a signal when the associated XT7 circuit breaker has operated. The accessory features one SPDT changeover contact and is designed for signalling circuits operating below 250 V AC/DC.
As an original ABB SACE Tmax XT electrical accessory, the 1SDA104811R1 is purpose-designed for the XT7 platform. It is specified to IEC 60947-2 and UL 489, is RoHS compliant and has a compact net weight of approximately 0.048 kg, making it suitable for circuit breaker status monitoring in industrial and commercial low-voltage distribution systems.
Auxiliary signalling contacts allow circuit breaker operating information to be transmitted to external equipment without relying on visual inspection of the breaker itself. The S52 contact in the ABB 1SDA104811R1 provides an electrical indication associated with the tripped condition, supporting remote supervision of the XT7 circuit breaker.
This functionality can be integrated into switchboard indication circuits, alarm systems, PLC inputs and other control equipment. By providing a dedicated changeover contact for trip signalling, the accessory helps operators and automation systems identify when a compatible XT7 circuit breaker has operated and requires attention.
