Why Choose the ABB AUX-C 1Q + 1SY L 24V DC XT5 F/P 1SDA104786R1 Auxiliary Contact?
The ABB 1SDA104786R1 is a genuine auxiliary contact assembly for ABB SACE Tmax XT5 circuit breakers, designed to provide remote electrical indication of circuit breaker status. It combines one changeover contact for open/closed indication (1Q) with one changeover contact for tripped indication (1SY), providing two independent status signals for monitoring and control systems.
Designed for voltages below 24 V DC, the AUX-C assembly is intended for compatible fixed and plug-in XT5 circuit breakers. The contacts are wired on the circuit breaker and the assembly is installed on the left-hand side, providing a purpose-designed solution for integrating breaker position and trip status into control panels, PLC systems and remote monitoring equipment.
As an original ABB SACE Tmax XT electrical accessory, the 1SDA104786R1 is designed specifically for the XT5 frame and provides two SPDT changeover auxiliary contacts. It complies with IEC 60947-2 and UL 489, has a net weight of approximately 0.127 kg and provides a compact solution for status signalling in industrial and commercial low-voltage distribution systems.
Key Advantages
- Provides both open/closed and tripped status indication from a compatible XT5 circuit breaker.
- Includes one 1Q changeover contact and one 1SY changeover contact.
- Designed for low-voltage signalling circuits below 24 V DC.
- Suitable for compatible fixed and plug-in ABB XT5 circuit breakers.
- Left-hand installation provides a defined mounting position within the breaker accessory system.
- Original ABB SACE Tmax XT accessory certified for IEC and UL applications.
Key Features
- ABB SACE Tmax XT accessory range.
- XT5 frame compatibility.
- 1Q open/closed changeover contact.
- 1SY tripped-indication changeover contact.
- Two SPDT auxiliary contacts in total.
- Designed for signalling voltage <24 V DC.
- Suitable for fixed and plug-in (F/P) XT5 configurations.
- Left-side installation.
- Wired directly on the compatible circuit breaker.
- Compliant with IEC 60947-2 and UL 489.
Circuit Breaker Status and Trip Signalling for ABB XT5
Auxiliary contacts allow a circuit breaker to communicate its operating state to external control and monitoring equipment. The 1Q contact provides open/closed position indication, while the 1SY contact provides a separate indication when the circuit breaker has tripped, allowing control systems to distinguish a protective trip from a normal change in breaker position.
The ABB 1SDA104786R1 combines these functions in a compact left-side accessory for compatible fixed and plug-in XT5 circuit breakers. Its low-voltage changeover contacts make it suitable for integration with PLC inputs, indication circuits, alarm systems, building management systems and other remote monitoring equipment requiring reliable breaker status information.
Typical Applications
- Remote open/closed indication for ABB SACE Tmax XT5 circuit breakers.
- Remote circuit breaker trip indication and alarm signalling.
- PLC and industrial automation input circuits.
- Low-voltage switchboard monitoring systems.
- Building management and electrical supervision systems.
- Industrial and commercial power distribution panels.
