ABB 1SDA054873R1 SOR-C T4-T5-T6 220..240Vac - 220..250Vdc Shunt Opening Release Accessory for Moulded Case Circuit Breaker

The ABB 1SDA054873R1 SOR-C T4-T5-T6 220..240Vac - 220..250Vdc is a shunt opening release accessory designed for ABB Tmax T4, T5, and T6 moulded case circuit breakers. This accessory enables remote tripping of the circuit breaker upon application of a control voltage in the 220–240 V AC or 220–250 V DC range, making it an essential component for automated protection and interlocking schemes in industrial control panels. Supplied as part of the Formula DSA / Tmax T series, the SOR-C T4-T5-T6 220..240Vac - 220..250Vdc integrates directly into the breaker body without modifying its rated performance.
