Why Choose the ABB AUX T4-T5-T6 1Q 1SY 24 V DC Auxiliary Contact?
The ABB 1SDA068797R1 is an auxiliary contact accessory designed for compatible ABB SACE Tmax T4, T5 and T6 moulded case circuit breakers. Configured as 1Q + 1SY with a 24 V DC signalling supply, it provides electrical indication of circuit-breaker operating and trip status for integration with control, monitoring and automation systems.
As part of the ABB SACE Tmax T4–T8 accessory range, this auxiliary signalling device is engineered for coordinated operation with the specified breaker families. Auxiliary contacts allow breaker status information to be transmitted to remote indication equipment, PLC inputs, control panels and supervisory systems.
The 1Q auxiliary contact provides circuit-breaker position/status signalling, while the 1SY signalling contact is used for trip indication. The 24 V DC configuration makes ABB order code 1SDA068797R1 particularly suitable for low-voltage control and automation circuits.

Reliable Circuit-Breaker Status Signalling
Auxiliary and signalling contacts allow the operating condition of a circuit breaker to be communicated electrically to equipment outside the breaker itself. This enables remote indication and integration with industrial control systems, helping operators and automation equipment identify breaker position and trip conditions without direct visual inspection.
The ABB 1SDA068797R1 combines 1Q and 1SY signalling functions in a configuration intended for compatible Tmax T4, T5 and T6 breakers. Its 24 V DC design is well suited to modern switchboards using low-voltage PLC, relay and supervisory control circuits.
Typical Applications
- ABB SACE Tmax T4, T5 and T6 circuit-breaker installations.
- Industrial switchboards and distribution panels.
- Remote circuit-breaker status indication.
- Trip signalling and alarm circuits.
- PLC and industrial automation interfaces.
- Building and power-management monitoring systems.
