1SDA062076R1 ABB SCR T7M-X1 24 V AC/DC Shunt Closing Release

Why Choose the ABB 1SDA062076R1 T7M-X1 Shunt Closing Release?

The ABB 1SDA062076R1 is a SCR shunt closing release designed for compatible ABB Tmax T7M and Emax X1 circuit-breaker operating systems. Rated for a 24 V AC/DC control supply, it enables the associated circuit breaker to be electrically closed by applying the appropriate control voltage to the release.

As part of the ABB Tmax T4–T8 accessory range, the SCR T7M-X1 provides a practical solution for remote and electrically controlled circuit-breaker closing. It is particularly suited to switchboards, automation systems and power distribution installations where circuit breakers must be operated from a remote control station, PLC or other electrical control circuit.

The SCR T7M-X1 24 V AC/DC version accepts both AC and DC control supplies at a nominal voltage of 24 V. Its dedicated compatibility with ABB T7M-X1 equipment and compact accessory format make it suitable for integration into industrial low-voltage switchgear requiring reliable electrically initiated closing.

Reliable Remote Circuit Breaker Closing

A shunt closing release allows a compatible circuit breaker to be closed through an electrical control signal rather than solely through local mechanical operation. This functionality is useful in automated power distribution systems, remotely controlled switchboards and installations where switching commands originate from a central control system.

The ABB 1SDA062076R1 operates from a nominal 24 V AC or 24 V DC control supply, making it suitable for commonly used low-voltage control circuits. Integration with compatible ABB T7M-X1 equipment provides a dedicated solution for electrically controlled closing in industrial and commercial power distribution applications.

Typical Applications

• Industrial low-voltage switchboards.
• Remote circuit-breaker closing systems.
• Automated power distribution installations.
• PLC and electrical control systems.
• Industrial and commercial switchgear assemblies.
• ABB Tmax T7M and Emax X1 circuit-breaker applications.
