Schneider Electric’s Square D GJL36050M05U Mag-Gard Motor Circuit Protector is a three-pole, unit-mount protector engineered for motor protection in 3‑phase circuits. Rated for 50 A, it operates up to 600 V AC and delivers a 65 kA short-circuit interrupting capacity at 480 V. The magnetic trip mechanism provides a trip range of 150–550 A, allowing fast isolation of faults while accommodating normal running currents near the 50 A rating. As part of the Mag-Gard GJL family, this UL-listed device combines rugged construction with compact form for panel installations and motor feeders. The U suffix indicates unit-mount installation, simplifying wiring and panel layout in control panels and switchgear. Designed for motor circuits and industrial environments, it provides rapid fault clearance to minimize equipment damage and downtime.
