Square D HJA36100U44XAABCSJYP is a 100A, 3-pole molded case circuit breaker designed for primary overcurrent and ground fault protection in industrial power distribution systems. It operates at a maximum voltage rating of 600V AC and features a solid-state trip unit with LSIG (Long-Time, Short-Time, Instantaneous and Ground Fault) protection functions, providing precise and adjustable coordination for branch and feeder circuits. The breaker utilizes an I-Line style plug-in connection for secure mounting in Square D panelboards and switchboards, with a compact frame size and a weight of 9 lb. It is UL listed and complies with industry standards, offering an interrupting capacity of 65kA at 480V AC for high-fault applications. Typical applications include motor control centers, industrial machinery, and commercial building electrical systems requiring reliable overcurrent and ground fault protection.
