The Square D HJL36050M72AABCSJ is a 3-pole molded case circuit breaker designed for magnetic-only protection in industrial power distribution systems. It is rated for 50A continuous current at 600V AC, with an interrupting capacity of 65kA at 480V AC for three-phase applications. This unit features a feed-thru connection style, an instantaneous (I) trip function, and weighs 7.95 lb, constructed for robust panelboard or switchboard installation. It complies with industry standards for overcurrent protection in motor control centers and heavy machinery. Typical applications include protecting branch circuits in manufacturing plants, commercial buildings, and process control systems where short-circuit protection is required without thermal overload sensing.
