ABB 1SDA053215R1 Current-Limiting Circuit Breaker

ABB 1SDA053215R1 S3X 200 1000V current-limiting circuit breaker is a three-pole, 160 A molded-case device designed for 1,000 V industrial installations. It belongs to ABB’s S3X family, featuring current-limiting protection with an Im rating of 1,600 A for fault conditions. The unit is intended for fixed mounting in 3-phase switchgear and is suitable for protecting feeders and motors in industrial power distributions that use 1,000 V systems. With a compact S3X 200 frame, this breaker provides fast fault clearance and reduced fault energy, helping to safeguard downstream equipment and improve uptime in demanding environments. Current-limiting action means only a portion of the fault current is allowed to pass to the protected circuit, mitigating damage to cables and devices during faults. The model designation 1SDA053215R1 identifies a 160 A device in ABB’s catalog, ensuring compatibility with ABB panel boards and S3X assemblies.
