Westinghouse FDB2020 Molded Case Circuit Breaker

The Westinghouse FDB2020 Molded Case Circuit Breaker is a 2-pole, 1-phase device rated for 20 A at 480 V, part of the Westinghouse FDB Frame family and built as a molded case circuit breaker for industrial power distribution. It uses a thermal-magnetic mechanism to provide overcurrent and short-circuit protection for branch circuits and equipment, and is designed for panel or switchboard mounting in installations operating at 50/60 Hz. This device is commonly used in control panels, switchboards, HVAC systems, automation controls, machinery power circuits, and conveyors within 480-volt networks, with maintenance teams, OEMs, and electrical integrators using it for replacement, retrofit upgrades, and ongoing maintenance of industrial infrastructure. Common replacements include Eaton FDB2020, Siemens HFD2020, and Square D FA2420, making it suitable for replacement, retrofit, or expansion within existing industrial electrical distribution.
