LAP36350MB - 350 Amp Circuit Breaker

LAP36350MB - 350 Amp Circuit Breaker

The LAP36350MB is a 350-amp, 3-pole LA molded case circuit breaker built for unit-mount applications. It is rated 22kA at 600 VAC, and the manufacturer describes it as providing thermal overload and magnetic short-circuit protection. If you're sourcing the LAP36350MB for existing equipment, the best approach is to match the whole breaker—not simply the 350A rating. Check the poles, voltage, interrupting rating, magnetic characteristics, unit-mount configuration, terminal arrangement, dimensions, and short-handle requirement.

Where It Works Best

The LAP36350MB makes the most sense for equipment that calls for a 350A, 3-pole LA unit-mount breaker with a shortened MB handle. That handle configuration is worth checking carefully with an existing panel or enclosure because the manufacturer ties it to proper panel-door clearance.
