Why Choose the ABB AUX-RTC T7M-X1 24 V DC Ready-to-Close Auxiliary Contact?
The ABB 1SDA062108R1 is a ready-to-close auxiliary contact (AUX-RTC) designed for compatible ABB SACE Tmax T7M and X1 circuit-breaker systems. Operating at 24 V DC, it provides an electrical indication that the circuit breaker meets the required conditions for a closing operation.
As part of the ABB SACE Tmax T4–T8 accessory range, the AUX-RTC supports remote status monitoring and control-system integration in low-voltage switchboards. The accessory incorporates a single changeover contact that can be incorporated into indication, interlocking and automation circuits to signal when the associated breaker is ready to close.
The 1SDA062108R1 is specifically identified as AUX-RTC T7M-X1 24 V DC CONS.CLOSING. Its cabled design and dedicated T7M-X1 compatibility make it suitable for industrial and commercial installations requiring dependable ready-to-close signalling from the circuit-breaker mechanism.

Reliable Ready-to-Close Status Signalling
A ready-to-close auxiliary contact provides an electrical status signal indicating that the associated circuit breaker satisfies the required conditions for a closing operation. This information can be used by switchboard controls, PLCs, remote indication systems and electrical interlocking logic before a closing command is issued.
The ABB 1SDA062108R1 provides this function for compatible T7M-X1 circuit breakers through a 24 V DC cabled changeover contact. It is particularly useful in automated power-distribution systems where breaker readiness must be confirmed as part of a controlled or remotely initiated closing sequence.
Typical Applications
- Ready-to-close indication for ABB T7M-X1 circuit breakers.
- Industrial low-voltage switchboards.
- Remote circuit-breaker status monitoring.
- PLC and automation control systems.
- Electrical interlocking and closing-control circuits.
- Commercial and infrastructure power-distribution systems.
