Why Choose the ABB 1SDA062109R1 AUX-RTC T7M-X1 Auxiliary Contact?
The ABB 1SDA062109R1 is an AUX-RTC ready-to-close auxiliary contact designed for compatible ABB Tmax T7M and Emax X1 circuit-breaker applications. Rated for use in signalling circuits up to 250 V AC/DC, it provides an electrical indication that the associated circuit breaker is in the correct condition and ready to receive a closing command.
As part of the ABB Tmax T4–T8 accessory range, the AUX-RTC provides a dedicated ready-to-close signalling function for electrically operated circuit breakers. It uses a single changeover contact (SPDT), allowing the status signal to be incorporated into switchboard indication circuits, interlocking systems, PLC inputs and other automation equipment.
The AUX-RTC T7M-X1 250 V AC/DC is a cabled auxiliary contact specifically intended for the T7M-X1 platform. By providing confirmation of the circuit breaker's readiness for closing, it supports reliable remote operation, electrical interlocking and status monitoring in industrial and commercial power distribution systems.
