ABB Circuit Breaker Accessory, Shunt Opening Release Type, 12VDC Operating Voltage - 1SDA066321R1 SOR-C XT1..XT4 F/P 12VDC

This circuit breaker accessory is a shunt opening release designed to provide remote tripping capability for Tmax XT breakers. It operates from a 12V DC control input and is intended to integrate with automation and electrical protection schemes where remote interruption of a breaker is required. The unit conforms to industry switchgear standards and fits within the Tmax XT range, enabling controlled opening of breakers in fault or control scenarios.

Features and Benefits:

• 12V DC operation allows straightforward low-voltage control
• Compatible with Tmax XT range for direct integration
• Conforms to IEC 60947-2 for recognised switchgear criteria
• Shunt opening function enables remote breaker tripping
• Meets RoHS and REACH for restricted-substance compliance

Applications

• Suitable for remote tripping in industrial automation panels
• Used with industrial motor control centres for fault clearance
• Ideal for integration into electrical distribution switchboards
• Can be used for safety interlock systems requiring remote opening

What electrical input is required to operate it?

It runs from a 12V DC control supply, triggering the opening mechanism when energised.

Which breakers will it work with mechanically and electrically?

It is intended for use with Tmax XT breakers and provides the shunt opening Interface those units accept.

What standards govern its use in switchgear assemblies?

Its design aligns with IEC 60947-2 requirements applicable to circuit-breaker accessories.

Are there environmental substance restrictions considered in the design?
