Why Choose the ABB AUX 1SY 400V AC XT7 Auxiliary Contact?
The ABB 1SDA104813R1 AUX 1SY 400V AC XT7 is an auxiliary trip-signalling contact designed for ABB SACE Tmax XT7 moulded-case circuit breakers. The accessory provides one SY changeover contact for external indication when the associated circuit breaker is in the tripped position, enabling clear breaker-status signalling within electrical distribution and control systems.
As part of the ABB SACE Tmax XT electrical accessory range, the 1SDA104813R1 is specifically designed for the XT7 frame. The SY function allows trip status to be communicated to external signalling, monitoring or automation equipment, making the accessory useful in switchboards where operators or control systems need remote indication that a protective trip has occurred.
This version is designed for AC signalling circuits below 400 V AC and incorporates one changeover (SPDT) auxiliary contact. Its dedicated XT7 compatibility and trip-indication function make it a practical accessory for industrial power distribution, switchgear monitoring and circuit breaker status systems.

Reliable Trip Indication for ABB Tmax XT7
Auxiliary signalling contacts allow information about a circuit breaker's operating condition to be communicated to external equipment without forming part of the main power circuit. The SY contact is dedicated to indicating that the circuit breaker is in the tripped position, helping distinguish a protective trip from normal breaker operation.
The ABB 1SDA104813R1 provides this function through a single changeover contact designed specifically for the Tmax XT7 platform. It can therefore support switchboard indicators, alarm circuits, PLC inputs and other monitoring equipment where reliable remote trip-status information is required.
Typical Applications
- ABB SACE Tmax XT7 moulded-case circuit breaker installations.
- Remote circuit breaker trip indication.
- Switchboard alarm and status signalling circuits.
- Industrial low-voltage distribution panels.
- Electrical protection and monitoring systems.
- PLC and industrial automation status inputs.
