Description

Rated for 400A applications, the Square D LAL3640035M1021 is a legacy L-Frame Mag-Gard motor circuit protector. It includes a factory-installed 120-240VAC shunt trip, enabling remote tripping for enhanced operational safety. This unit mount device integrates seamlessly into existing motor control centers via standard lug connections. While currently replaced by the PowerPacT LGL36400U31X, it remains essential for maintaining older systems with its 1750-3500A adjustable magnetic trip.
