Schneider Electric LAP36300MT Molded Case Circuit Breaker

The Schneider Electric LAP36300MT is a three‑pole molded case circuit breaker (MCCB) rated for 300 A at up to 600 V, built to protect three‑phase feeders and equipment in commercial and industrial distribution panels. It belongs to the PowerPact LAP family and uses thermal‑magnetic trip technology with both long‑time and instantaneous protection, allowing it to respond to overloads while still permitting normal startup currents when within set limits. This unit‑mount breaker is designed for panel installation with top‑feed lugs and load‑side lug terminals, providing flexible terminations and straightforward replacement in existing equipment. The LAP36300MT carries a 22 kA short‑circuit withstand rating at 600 VAC and a 250 VDC interrupt rating, offering robust protection for circuits powered from industrial power rails. In practice, it is used as primary protection for three‑phase feeders in machine rooms, switchgear, and large distribution panels, where reliable overcurrent protection and quick disconnection are critical for protecting wiring, motors, and downstream devices.
