Description

The Westinghouse FB3020 is a reliable 3-pole thermal magnetic circuit breaker designed for industrial and commercial electrical distribution systems. Rated at 20 amps and 600 VAC, it provides robust protection against overloads and short circuits through its thermal-magnetic trip mechanism, which combines thermal sensing for overloads and magnetic sensing for faults. This model is part of the FB series, known for its compact design and high interrupting capacity, making it suitable for applications in panelboards, switchboards, and motor control centers. Key features include a molded case construction for durability, lug terminals for easy installation, and compatibility with Westinghouse and Eaton systems (as Westinghouse was acquired by Eaton). Advantages over similar products include its proven reliability in legacy systems, cost-effectiveness for replacements, and ability to handle interrupting ratings up to 14kA at 600V. Drawbacks may include limited availability of new units due to the age of the product line and potential incompatibility with modern smart grid integrations. Ideal for protecting motors, lighting, and general circuits in manufacturing, utilities, and building infrastructure. Based on attached images, the unit appears new in original packaging, with no visible wear, serial/style numbers visible (e.g., Style No. 4975D71G35), and no attached accessories.
