The Square D LJL36400U31XSA is a 3‑pole, 400 amp PowerPact® L‑Frame molded case circuit breaker from Schneider Electric’s Square D brand, engineered to provide high‑performance overcurrent protection in commercial and industrial power distribution systems. Rated for use up to 600 VAC, this breaker is suited for applications including feeder protection, main disconnect duty, and branch‑circuits in large panelboards and switchboards. Its PowerPact L frame construction delivers a rugged, compact design that balances high current capacity with space‑efficient installation.
Electrically, the LJL36400U31XSA features a MicroLogic 3.3 electronic trip unit with LI (long‑time and instantaneous) trip functions, providing dependable protection against overloads and short‑circuit events. It carries interrupting rating of 65kA@480V, ensuring safe interruption of fault currents in industrial environments with substantial available fault energy. Rated at 80% continuous current, this breaker helps engineers meet coordination and selective protection requirements while minimizing nuisance trips.
Mechanically, the LJL36400U31XSA uses a Feed-Thru connection with line‑side lugs and terminal‑nut load connections for secure, high‑current wiring. The breaker includes features such as dual‑break rotating contacts to reduce peak let‑through during faults and an integral push‑to‑trip button for manual testing and maintenance. Designed to comply with UL 489, CSA, NEMA, and IEC standards, this PowerPact breaker integrates seamlessly into industrial or commercial electrical systems, offering reliable performance and long‑term service life.
