Description
The Westinghouse HKB3250F is a robust 3-pole molded case circuit breaker designed for industrial and commercial electrical distribution systems. Featuring a 250A frame size with an interchangeable HKB3150T trip unit rated at 150A, this breaker provides reliable overcurrent protection for circuits up to 600V AC. It is part of the Mark 75 series, known for its high interrupting capacity, making it suitable for applications in motor control centers, panelboards, and switchgear where fault currents can be significant. Key benefits include thermal-magnetic trip mechanism for precise protection against overloads and short circuits, compact design for easy installation, and compatibility with legacy Westinghouse systems (now supported by Eaton). Advantages over similar products include superior interrupting ratings (e.g., 65kA at 240V), durability in harsh environments, and cost-effectiveness for retrofits. Drawbacks may include limited availability of parts due to the age of the series and potential need for professional testing before reuse. This unit appears used but has been cleaned and tested, showing minor wear on the casing and terminals, with no visible damage to critical components. Ideal for protecting motors, transformers, and feeders in manufacturing plants or data centers. For detailed specs, refer to Eaton's legacy Westinghouse documentation.
