Westinghouse Electric Corporation JD3250F Circuit Breaker

The Westinghouse JD3250F is a 3-pole, 250 Amp molded‑case circuit breaker rated for 600 V AC, engineered to interrupt overcurrent and short‑circuit faults in three‑phase power systems. With fixed panel mounting, it is commonly installed in switchgear assemblies, motor control centers, industrial machinery, and commercial electrical panels where thermal‑magnetic protection is required for high‑demand circuits. The JD3250F provides branch‑circuit and equipment protection through a thermal‑magnetic trip mechanism, designed for commercial and industrial electrical protection systems. Typical applications include manufacturing facilities, industrial automation, HVAC equipment, and general power distribution and motor control scenarios where 250 A three‑phase protection supports safe, continuous operation. Common replacements listed in specifications are Eaton JD3250F, Cutler‑Hammer JD3250F, and Square D KA36250.
