Schneider Electric LJL36600U43XEN Circuit Breaker

Schneider Electric's Square D PowerPact LJL36600U43XEN is a 600 A, three-pole molded‑case circuit breaker in the PowerPact L-Frame family, designed for 600 VAC service with a 25 kA interrupting rating and line-to-load lugs on both sides for through-feed connections. Powered by a MicroLogic 5.3A electronic trip unit (LSI), it provides long-time, short-time with a fixed delay, and instantaneous protection to guard feeders and downstream equipment from overloads and short circuits. The unit is UL 489 listed and carries additional certifications including CSA, NEMA, NMX, VDE, BS, CCC, IEC, and CE marking, making it suitable for use in diverse international installations. Typical applications include acting as a main panel disconnect in control panels or as a protective feeder breaker in industrial switchgear, where a compact L-Frame MCCB with an electronic trip is needed to meet protective coordination and fast isolation requirements in 3-phase systems.
