Westinghouse FD2150 Bolt On Industrial Circuit Breaker

The Westinghouse FD2150 Bolt-On Molded Case Circuit Breaker is a 150 A, 600 V two-pole device built for industrial power distribution and branch-circuit protection. Mounted on a bolt-on frame (FD series), it delivers thermal-magnetic overcurrent protection with a 25 kA interrupt rating for 1-phase circuits at 50/60 Hz. Commonly installed in switchboards, control panels, HVAC systems, and industrial machinery, it protects high-amperage single-phase distribution circuits and connected equipment. Maintenance teams, OEMs, and electrical integrators use the FD2150 for replacement, retrofit upgrades, and ongoing protection of industrial electrical infrastructure.
