Why Choose the ABB SOR XT1..XT4 380–440 V AC?
The ABB 1SDA066318R1 is a SOR shunt opening release designed for compatible ABB SACE Tmax XT1, XT2, XT3 and XT4 moulded case circuit breakers. Rated for a control supply of 380–440 V AC, it provides an electrical means of remotely initiating circuit-breaker opening.
A shunt opening release is used when a breaker must be tripped by an external control signal rather than solely by its protection unit or local operating mechanism. This makes the SOR useful in switchboards, automation systems and safety circuits where remote electrical opening of a compatible Tmax XT breaker is required.
With compatibility spanning XT1 through XT4, ABB order code 1SDA066318R1 provides a clearly specified accessory for several frames within the Tmax XT platform. Its 380–440 V AC rating must be matched to the installation's control circuit when selecting the release.

Remote Opening for Tmax XT Circuit Breakers
A shunt opening release provides a circuit breaker with an electrically controlled trip function. When the appropriate control signal is applied to the release, it actuates the opening mechanism of the compatible breaker, allowing remote shutdown commands to be incorporated into electrical control and protection schemes.
The ABB 1SDA066318R1 is specifically rated for 380–440 V AC and is intended for compatible Tmax XT1 through XT4 circuit breakers. This combination makes it suitable for installations where the available control voltage and required breaker frame correspond to this SOR configuration.
Typical Applications
- Remote opening of compatible ABB SACE Tmax XT circuit breakers.
- Industrial low-voltage switchboards.
- Electrical distribution and control panels.
- Machine and process control systems.
- Electrically initiated shutdown circuits.
- Building and industrial automation systems.
