LAL3640031M - 400 Amp Motor Circuit Protector

LAL3640031M - 400 Amp Motor Circuit Protector

The LAL3640031M is a 400-amp, 3-pole LA motor circuit protector for your motor-control applications that require a magnetic-only protective device. Rated for 600VAC, it uses a unit-mount configuration and has lugs on both the line and load sides. Replacing an existing unit? Take a few minutes to compare the complete specification—not just the 400A rating. Poles, voltage, magnetic settings, mounting, terminals, and dimensions all matter when determining whether the LAL3640031M is the right form, fit, and functional replacement. Properly selected, adjusted, installed, and kept within its specified application, it's built to last.
