Westinghouse Electric Corporation JD3250F Circuit Breaker

The Westinghouse JD3250F Circuit Breaker is a 3-pole molded‑case device, Part Number JD3250F, in the JD series, rated for 250 A and 600 V AC for industrial and commercial electrical distribution. It provides thermal‑magnetic overcurrent and short‑circuit protection for high‑capacity three‑phase circuits and equipment, with a thermal‑magnetic trip that responds to overloads and faults, and is suitable for switchgear assemblies, motor control centers, industrial machinery, and commercial electrical panels. As a fixed‑mount, panel‑mounted unit, it is designed for branch circuit and equipment protection within commercial and industrial power systems. Maintenance teams, electricians, and facility operators use this breaker for replacement of aging protection devices, electrical system upgrades, and preventative maintenance of power distribution infrastructure. Common applications include manufacturing facilities, industrial automation systems, HVAC equipment, power distribution systems, and motor control applications where reliable 250 A three‑phase protection and fault interruption are critical for safe operation. Common replacements include Eaton JD3250F, Cutler‑Hammer JD3250F, and Square D KA36175. Construction features molded‑case protection with a fixed mount for installation in switchgear and distribution systems, providing dependable interruption in commercial and industrial electrical protection systems.
