Westinghouse FD2100 Molded Case Circuit Breaker

The Westinghouse FD2100 Molded Case Circuit Breaker is a 100 Amp, 600 Volt, 2-pole device in the FD Frame series designed for thermal-magnetic overcurrent and short-circuit protection. Typically installed in switchboards, motor control centers, industrial automation panels, and manufacturing equipment, it provides dependable branch-circuit protection for high-amperage power distribution. Maintenance teams, OEMs, and electrical integrators use the FD2100 for replacement, retrofit, and ongoing protection of industrial electrical infrastructure. It is panel- or switchboard-mounted and supports single-phase and industrial distribution systems operating at 50/60 Hz. Common applications include motor control systems, HVAC infrastructure, conveyors, automation systems, and other 600-volt equipment. For compatibility, common replacements include Eaton FD2100, Siemens HFD2100, and Square D FA24100.
