Why Choose the ABB 1SDA104810R1 AUX 1S52 24V XT7?
The ABB 1SDA104810R1 is a dedicated S52 auxiliary contact for tripped indication designed for ABB SACE Tmax XT7 moulded-case circuit breakers. Designated AUX 1S52 24V XT7, it provides one auxiliary contact for signalling a circuit-breaker trip condition to external monitoring, alarm or automation equipment.
As part of the ABB SACE Tmax XT electrical accessory range, the 1SDA104810R1 provides a purpose-designed signalling interface for compatible XT7 installations. The S52 function enables remote indication of a protective trip, helping operators and control systems distinguish a tripped circuit breaker within industrial power distribution equipment.
The auxiliary contact is intended for AC/DC signalling circuits below 24 V and provides one S52 contact. For the XT7 application, the S52 tripping signal is available when a YU or YO2 coil is installed in the dedicated slot, making the accessory suitable for appropriately configured XT7 circuit-breaker systems.
