Why Choose the ABB 1SDA062077R1 T7M-X1 Shunt Closing Release?
The ABB 1SDA062077R1 is a SCR T7M-X1 shunt closing release designed for compatible ABB Tmax T7M and Emax X1 circuit-breaker applications. Operating from a nominal 30 V AC/DC control supply, it enables the associated circuit breaker to be electrically closed through an appropriate remote or local control circuit.
As part of the ABB Tmax T4–T8 accessory range, the SCR provides a dedicated solution for electrically initiated circuit-breaker closing. This functionality is particularly useful in industrial switchboards, automated power distribution systems and installations where closing commands are issued from control panels, PLC systems or other remote control equipment.
The SCR T7M-X1 30 V AC/DC is a cabled shunt closing release specifically associated with the T7M platform. Its ability to operate from either a 30 V AC or 30 V DC supply provides flexibility when integrating the accessory into low-voltage switchgear control circuits.

Reliable Remote Circuit Breaker Closing
A shunt closing release allows a compatible circuit breaker to be closed electrically rather than requiring direct manual operation at the breaker. When the specified control voltage is applied, the release operates the compatible closing mechanism, enabling the circuit breaker to form part of remotely controlled or automated electrical distribution equipment.
The ABB 1SDA062077R1 operates from a nominal 30 V AC or 30 V DC supply, making it suitable for control systems designed around this voltage level. Its dedicated T7M-X1 configuration provides an ABB-engineered solution for industrial switchboards where reliable electrical closing and integration with control circuitry are required.
Typical Applications
- Industrial low-voltage switchboards.
- Remote circuit-breaker closing systems.
- Automated power distribution installations.
- PLC-controlled electrical distribution systems.
- Industrial and commercial switchgear assemblies.
- ABB Tmax T7M and Emax X1 circuit-breaker applications.
