ABB 1SDA054879R1 PS-SOR-C T4-T5-T6 110..120Vac xPERM.SERV Shunt Opening Release Accessory for Moulded Case Circuit Breaker

The ABB 1SDA054879R1 PS-SOR-C T4-T5-T6 110..120Vac xPERM.SERV is a shunt opening release accessory designed for use with ABB Tmax T series moulded case circuit breakers (T4, T5, and T6 frames). The PS-SOR-C T4-T5-T6 110..120Vac xPERM.SERV triggers the circuit breaker to open upon receiving a voltage signal in the 110–120 V AC range, enabling remote tripping and integration into automated protection and control systems. Compact and lightweight at 0.17 kg, this accessory is a critical component for engineers specifying reliable, remotely actuated circuit interruption in industrial control panels and power distribution assemblies.
