Westinghouse JA3225W Circuit Breaker is a 3‑pole molded‑case device rated for 225 A at 600 V AC, designed for bolt‑on panel mounting with mounting bolts included. As a thermal‑magnetic breaker in the JA series, it provides overcurrent and short‑circuit protection for high‑capacity three‑phase power circuits in commercial and industrial electrical systems, and is commonly installed in panelboards, switchgear assemblies, motor control centers, and industrial panels where dependable fault interruption is required. It is used by maintenance teams, electricians, and facility operators for replacement of aging protection devices, electrical system upgrades, and preventive maintenance of power distribution infrastructure in manufacturing facilities, commercial buildings, HVAC systems, and industrial automation equipment. Common replacements include Square D KA36200, as well as Eaton JA3200W and Cutler‑Hammer JA3200W, with hardware included for bolt‑on installation.
