Westinghouse EHB1020L is a 1-pole molded case circuit breaker from the AB DE-ION family, designed for thermal magnetic overcurrent protection with LI (Long-Time and Instantaneous) trip functions. It is rated for 20A continuous current at 277VAC, with an interrupting capacity of 10kA at 277V, and features a feed-thru connection configuration for single-phase applications. The unit weighs 1 lb and is constructed as a compact molded case breaker for panelboard installation. This breaker complies with industry standards for overcurrent protection in commercial and industrial electrical distribution systems. Typical applications include branch circuit protection in lighting, appliance, and motor control panels where reliable short-circuit and overload interruption is required.
