LXP36400 - 400Amp Circuit Breaker

LXP36400 - 400Amp Circuit Breaker

The LXP36400 is a 400-amp, 3-pole molded case circuit breaker designed for use in your AC electrical distribution systems operating at 60Hz. It uses a thermal-magnetic operating mechanism with a Micrologic electronic trip unit to provide overload and short-circuit protection. This breaker is rated for 35 kA at 600 VAC, 65 kA at 480 VAC, and 100 kA at 240 VAC. It is calibrated for operation in 40°C ambient conditions and includes load-side lugs. When you're replacing an existing LXP36400, matching the amperage, pole configuration, interrupting rating, and voltage is important to help you ensure compatibility with the equipment it serves. Built to last, this breaker is intended to provide the same form, fit, and function as the original device.
