Why Choose the ABB 1SDA062103R1 AUX T7 1Q + 1SY 24V DC Auxiliary Contact?
The ABB 1SDA062103R1 is an auxiliary contact accessory for ABB SACE Tmax T7 circuit breakers. Identified as AUX T7 1Q + 1SY 24V DC, it combines one changeover contact for circuit breaker open/closed position signalling with one changeover contact for automatic trip indication.
Designed for 24 V DC signalling circuits, the accessory provides two distinct status signals from the circuit breaker. The 1Q contact communicates the breaker open or closed state, while the 1SY contact provides indication when the breaker has operated automatically following a trip event.
By providing both operating-position and trip-status information, the 1SDA062103R1 supports remote indication, switchboard monitoring and integration with suitable control or automation systems. It is a genuine ABB Tmax T accessory designed specifically for compatible T7 circuit breaker installations.

Circuit Breaker Position and Trip Status Signalling
Auxiliary contacts allow a circuit breaker's mechanical state to be represented electrically in monitoring and control circuits. With the ABB 1SDA062103R1, the 1Q changeover contact indicates whether the compatible T7 breaker is open or closed, enabling its operating position to be monitored remotely without relying solely on visual inspection of the breaker.
The additional 1SY changeover contact provides a separate signal when the circuit breaker has opened automatically due to a trip. This distinction helps control systems differentiate an automatic protection operation from normal switching, making the accessory useful for alarms, status displays, control panels and automated monitoring systems operating with 24 V DC signalling.
Typical Applications
- ABB Tmax T7 circuit breaker status monitoring.
- Open and closed position indication on switchboards.
- Automatic trip indication and alarm circuits.
- Industrial control and automation systems.
- Building and infrastructure power monitoring systems.
- Remote status signalling using 24 V DC control circuits.
