Description
Rated for 400A at 600VAC, this Square D Mag-Gard motor circuit protector delivers instantaneous short-circuit defense for industrial machinery. It is engineered to work alongside separate overload relays to provide complete motor branch circuit protection. The unit-mount L-Frame breaker fits standard motor control centers and NEMA enclosures. It serves as a replacement for legacy systems, with the LJL36400M38X acting as its modern substitute. Includes an adjustable 1250-2500A magnetic trip.
