Square D LX36400 – 400A 3 Pole Molded Case Circuit Breaker Cheap

Rated for 400 amps, this legacy L-Frame circuit breaker utilizes a Micrologic trip unit to provide highly accurate True RMS sensing. It easily installs into Square D I-Line switchboards, making it ideal for industrial facilities requiring 65kAIC at 480V. When replacing this discontinued model, facilities should use the PowerPact LJA36400U43X along with an HNM1BL filler plate to accommodate the dimensional differences in the enclosure.
