LAL3640030M - 400 Amp Motor Circuit Protector

LAL3640030M - 400 Amp Motor Circuit Protector

The LAL3640030M is a 400-amp, 3-pole LA motor circuit protector with thermal-magnetic trip technology. Its electrical ratings include 22kA at 600VAC and 10kA at 250VDC, and it uses a unit-mount configuration with lugs on both the line and load sides. If you're replacing a motor circuit protector in existing equipment, don't decide on amperage alone. The mounting arrangement, interrupting rating, terminals, dimensions, and three-pole configuration must match the application.

Where It Works Best

The LAL3640030M is a practical fit for existing or legacy equipment designed around a 400A, 3-pole LA motor circuit protector with matching electrical and mechanical requirements.

Start with the numbers: 400A, three poles, 22kA at 600VAC, and 10kA at 250VDC. If those match the application, move on to the physical side of the job. This model is unit-mounted, has line and load lugs, uses AL400LA terminals, and measures 11 x 6 x 5.84 inches.
