Westinghouse FD3125LS Molded Case Circuit Breaker

The Westinghouse FD3125LS molded case circuit breaker provides 125 A of three‑phase overcurrent protection at 600 V for industrial power systems. It uses thermal‑magnetic protection, has an 18 kA interrupt rating, and belongs to the FD frame with LS suffix, configured as a 3‑pole, panel‑ or switchboard‑mounted device for 50/60 Hz networks. Typical applications include motor control centers, switchboards, industrial automation panels, and manufacturing equipment requiring high‑amperage protection, as well as HVAC infrastructure and conveyor equipment. Maintenance teams, OEMs, and electrical integrators rely on this breaker for replacement, retrofit upgrades, and maintenance of existing industrial electrical infrastructure.
