LAL3640035M - 400 Amp Motor Circuit Protector

LAL3640035M - 400 Amp Motor Circuit Protector

Protect your motor circuits with confidence using the Schneider Electric LAL3640035M — a high-performance motor circuit protector built for industrial and commercial applications. With its 3-pole thermal-magnetic design and 400 A rating, it delivers dependable disconnection for both AC and DC systems (up to 600 VAC / 250 VDC). Its adjustable amperage pick-up setting enables precise coordination with motor starters, and compatibility with standard LA lugs and accessories makes it a practical choice for retrofits or new installations.

Key Features and Benefits

• Magnetic Trip Protection: Automatically cuts power on severe fault currents, safeguarding motor circuits when short-circuits occur.
• Adjustable Pick-Up Setting: Fine-tune triggering levels to work in harmony with your motor starter and system protection plan.
• LA Accessory Compatibility: Uses the same lugs and add-ons as equivalent LA circuit breakers, simplifying integration.
• Unit Mount Design: Installs quickly and cleanly in motor control centers or switchgear assemblies.
• Heavy-Duty Build: Engineered with materials that last under industrial loads and continuous cycling.
• Eco-Conscious Compliance: RoHS and REACH compliant, with no added mercury or halogens.
