ABB 1SDA054876R1 PS-SOR is a 24 V AC/DC permanent-service shunt opening release designed for remote electrical opening of compatible ABB SACE Tmax T4, T5 and T6 circuit breakers.
£176.99
The ABB 1SDA054876R1 is a PS-SOR shunt opening release for permanent service designed for remote electrical opening of compatible ABB SACE Tmax T4, T5 and T6 moulded case circuit breakers. As part of the ABB Tmax circuit breaker accessory range, it provides dependable remote tripping while supporting continuous energisation in control and automation applications.
Unlike a conventional shunt opening release intended for short-duration operation, the PS-SOR is specifically designed for permanent service. Its low power consumption allows the release to remain continuously supplied, making it particularly suitable for industrial control schemes where sustained energisation of the opening release is required.
With a rated control supply of 24 V AC/DC, the 1SDA054876R1 provides flexible compatibility with both AC and DC control circuits. It is designed for ABB SACE Tmax T4, T5 and T6 circuit breakers and has a power consumption of approximately 4 VA on AC or 4 W on DC.
A shunt opening release allows a compatible circuit breaker to be opened remotely by applying an electrical control signal. This enables circuit breakers to be incorporated into automation, protection, emergency shutdown and remote isolation systems without requiring manual operation directly at the breaker.
The ABB PS-SOR differs from standard shunt opening releases through its permanent-service design. For the Tmax T4, T5 and T6 range, the PS-SOR has substantially reduced power consumption and can be continuously supplied, providing a practical solution for control circuits that require the opening release to remain energised for extended periods.

The ABB 1SDA054876R1 is a permanent-service shunt opening release used to remotely open compatible ABB SACE Tmax T4, T5 and T6 circuit breakers using an electrical control signal.
The release is designed for use with ABB SACE Tmax T4, T5 and T6 moulded case circuit breakers.
The PS-SOR operates from a 24 V AC/DC control supply, allowing it to be used with compatible AC or DC control circuits.
Permanent service means the release is designed to remain continuously supplied. The PS-SOR uses approximately 4 VA on AC or 4 W on DC, significantly reducing the power required for continuous operation.
It is typically fitted to a compatible ABB Tmax T4, T5 or T6 circuit breaker in an electrical switchboard, distribution panel or industrial control system where remote or continuously energised breaker opening control is required.
ABB SACE Tmax circuit breaker accessories provide flexible control and protection functionality for industrial and commercial power distribution systems, with the PS-SOR permanent-service release providing low-power remote opening capability for compatible Tmax T4, T5 and T6 circuit breakers.
