Industrial 314C531G20 Molded Case Circuit Breaker

Westinghouse HF3020 3-pole, 20 A molded case circuit breaker (alternate part number 314C531G20) is designed for industrial electrical distribution and branch-circuit protection. As part of the HF Frame series, this 3‑phase device uses a thermal‑magnetic trip to provide overcurrent and short‑circuit protection in panels, switchboards, motor control centers (MCCs), and other industrial control panels operating at 50/60 Hz. It is panel- or switchboard-mounted for power distribution and motor control systems, suitable for low-to-medium amperage three‑phase equipment in demanding environments such as HVAC infrastructure, conveyors, automation equipment, and manufacturing machinery. Common replacements include Eaton HF3020, Siemens HFD3020, and Square D LA3620.
