LAL3640032M - 400 Amp Motor Circuit Protector
When you’re looking for dependable motor protection, the LAL3640032M Motor Circuit Protector delivers. Built for heavy-duty duty, this 3-pole unit from Schneider Electric handles up to 400 A at 600 VAC and is engineered to respond instantly when trouble strikes. Its magnetic trip design isolates short circuits fast, helping keep your motors and downstream equipment safe. The adjustable amperage pick-up setting lets you fine-tune coordination with motor starters, so you get exactly the protection your system needs without unnecessary tripping. Designed to pair seamlessly with LA-series lugs and accessories, it slips into many existing setups with minimal hassle.
Key Features and Benefits
- High Current Capacity: Rated for 400 A service—suitable for large motors and industrial drives.
- Adjustable Pick-Up Levels: Customize the trip threshold to match with motor starters, improving selective coordination.
- Magnetic Trip Protection: Fast response to short-circuit events protects motors and wiring from severe faults.
- High Interrupting Ratings: Able to interrupt 22 kA at 600 V AC, 30 kA at 480 V AC, and 42 kA at 240 V AC, plus 10 kA at DC levels.
- Line & Load Lugs: Feed-through connections simplify installation in tight switchgear or control enclosures.
- Adjustable Torque Terminals: Terminals accept a wide range of copper or aluminum conductor sizes (AWG 1 to 600 kcmil).

Where It Works Best
- This motor circuit protector shines in industrial environments where dependable and selective protection is critical. Use it in motor control centers, manufacturing plants, water treatment facilities, heavy mechanical systems, and any setting where motors require fast isolation under fault conditions. Its adjustable trip settings help it coordinate with starter devices, reducing downtime from nuisance trips. Because it accepts broad wire sizes and standard lugs, integration into upgraded or expanded systems is fairly straightforward.
