Westinghouse F-3025U Molded Case Circuit Breaker

The Westinghouse F-3025U Molded Case Circuit Breaker is a 3-pole, 25 A molded‑case breaker used to protect feeders and branch circuits in industrial electrical distribution. It is rated for 480 VAC (up to 600 VAC system rating) with a 14 kA interrupting capacity and uses a thermal‑magnetic trip unit to provide long-time and instantaneous protection at 50/60 Hz. This bolt‑on MCCB has line and load lug terminals and is part of the Westinghouse/F series with an F frame, designed for 3‑phase systems and 40°C ambient operation. Common applications include panelboards, switchboards, motor control centers, and industrial power systems in manufacturing facilities, HVAC, pumps, conveyors, and other continuous‑duty loads requiring reliable three‑phase overcurrent protection. For replacements or retrofits, common equivalents include Westinghouse RF3025, Eaton FDB3025, and Cutler‑Hammer FDB3025.
