Why Choose the ABB 1SDA051369R1 AUX T1...T6 3Q 1SY Auxiliary Contact?
The ABB 1SDA051369R1 is a genuine auxiliary contact and trip-signalling accessory designed for compatible ABB SACE Tmax T1, T2, T3, T4, T5 and T6 moulded-case circuit breakers. As part of the ABB Tmax electrical accessory range, it provides remote electrical indication of circuit-breaker operating status and trip condition for monitoring, control and automation systems.
The accessory features a 3Q + 1SY contact configuration. Three Q changeover contacts provide electrical indication of the circuit breaker’s open or closed position, while the dedicated SY changeover contact signals when the breaker has opened because of a protective or release operation. This combination provides useful status information for switchboards, PLC systems, alarm circuits and remote supervisory equipment.
The 1SDA051369R1 is an uncabled 250 V AC/DC version intended for field wiring during installation. Its broad Tmax compatibility makes it a practical signalling accessory for industrial power distribution systems requiring reliable breaker status feedback.

Reliable Circuit-Breaker Status and Trip Signalling
Auxiliary contacts allow the mechanical state of a circuit breaker to be represented electrically within a control or monitoring system. This enables operators, PLCs and supervisory equipment to determine whether a breaker is open or closed without requiring direct visual inspection of the device.
The dedicated SY contact adds separate trip information, allowing a control system to distinguish a protective trip from normal breaker status. This makes the ABB 1SDA051369R1 particularly useful in automated switchboards where alarms, interlocks and remote diagnostics depend on accurate circuit-breaker feedback.
Typical Applications
- Industrial low-voltage switchboards.
- Power distribution and protection panels.
- Remote circuit-breaker status indication.
- PLC and industrial automation interfaces.
- Trip alarm and fault-signalling circuits.
- Electrical interlocking and supervisory control systems.
