Square D LX36350 – 350A 3 Pole Molded Case Circuit Breaker Express Delivery

Built for heavy-duty commercial environments, this 350-amp MCCB features solid-state LSI protection to coordinate complex electrical systems. The breaker mounts into traditional Square D I-Line panelboards using standard load-side lugs. For modern upgrades, Schneider Electric recommends substituting with the LJA36400U43X PowerPact model, utilizing an HNM1BL adapter plate and dialing the microprocessor down to 350 amps.
