Why Choose the ABB 1SDA066443R1 AUX-C Auxiliary Contacts?
The ABB 1SDA066443R1 is a genuine ABB wired auxiliary contact assembly designed for compatible SACE Tmax XT2 and XT4 moulded case circuit breakers. Identified by ABB as AUX-C 2Q 400Vac XT2-XT4 W, it provides two changeover contacts for electrical indication of the associated circuit breaker’s open and closed position.
The AUX-C designation identifies the cabled auxiliary contact version, while 2Q denotes two changeover contacts. This particular accessory is intended for withdrawable (W) XT2 and XT4 circuit breakers, providing a dedicated wired interface for communicating breaker position to external signalling, monitoring and control equipment.
Rated for signalling applications up to 400 V AC, the 1SDA066443R1 is suitable for industrial switchboards, automation systems and power distribution equipment requiring remote circuit breaker status indication. Its two independent changeover contacts provide flexibility for applications where open / closed position information must be incorporated into multiple control, indication or interlocking functions.
Key Advantages
- Genuine ABB wired auxiliary contact assembly for SACE Tmax XT circuit breakers.

Position Signalling for Withdrawable ABB Tmax XT Circuit Breakers
Auxiliary contacts allow the mechanical position of a circuit breaker to be communicated electrically to external equipment. The ABB 1SDA066443R1 provides two changeover contacts for open / closed position signalling, allowing the status of a compatible XT2 or XT4 withdrawable circuit breaker to be incorporated into switchboard indication, automation, interlocking and supervisory control systems.
Unlike the corresponding F/P version for fixed and plug-in breakers, the 1SDA066443R1 is specifically configured for withdrawable XT2 and XT4 circuit breakers. Its wired AUX-C construction and two independent changeover contacts make it particularly useful where breaker status must be communicated to more than one signalling or control function within an industrial electrical installation.
Typical Applications
- Open / closed position indication for ABB SACE Tmax XT2 withdrawable circuit breakers.
- Open / closed position indication for ABB SACE Tmax XT4 withdrawable circuit breakers.
- Industrial switchboard status and signalling circuits.
- PLC and automation-system digital inputs.
- Electrical interlocking and supervisory control systems.
- Withdrawable circuit breaker installations in machinery and power distribution equipment.
