LAL3640033M - 400 Amp Motor Circuit Protector

LAL3640033M - 400 Amp Motor Circuit Protector

If you're managing industrial motors and need a solid way to protect them from overloads or short circuits, the Schneider Electric LAL3640033M has your back. Designed specifically for demanding, high-energy environments, this 3-pole motor circuit protector is rated for 400 amps and built to handle serious fault conditions—like 22,000 amps at 600 volts AC. It’s not just tough; it’s smart, with a thermal-magnetic trip system that reacts when something goes wrong, cutting power fast to prevent damage.

What really makes this unit stand out is how easy it is to install. The unit-mount design fits right into your panel or motor control center without a headache. Whether you're upgrading old gear or setting up a new system, it's made to drop in and get to work.
