Engineered for demanding electrical systems, the Square D PowerPact LDL36250U33X is a L-Frame 250A 3-pole molded case circuit breaker with standard interrupting capacity. Rated at 25kA@240V, 18kA@480V, 14kA@600V and operating at 600V AC, it provides reliable and consistent protection for power distribution infrastructure applications. The LDL36250U33X features a MicroLogic 3.3S LSI electronic trip unit providing adjustable long-time delay, short-time delay, instantaneous, and ground fault protection settings for precise overcurrent coordination. This advanced electronic trip technology enables optimized protection curves, selective coordination with upstream and downstream protective devices, and significantly enhanced system reliability. Configured for unit mount installation, the LDL36250U33X utilizes lug (unit mount) connections with AL400L61K3/AL600LS52K3 terminations designed for reliable conductor termination. The unit accommodates (1) 2-600 kcmil conductors within compact overall dimensions of 10.24" H x 5.51" W x 5.67" D weighing ~25 lbs, optimizing installation density in electrical distribution equipment. UL 489 listed and CSA C22.2 No.5 certified, the LDL36250U33X meets IEC/EN 60947-2 international standards for global project specification and acceptance. Applications include feeder circuit protection, branch circuit protection, motor control center installations, panelboard and switchboard applications, and industrial power distribution systems requiring L-Frame frame-class protection capabilities. The LDL36250U33X exemplifies Schneider Electric's PowerPact platform engineering excellence, delivering consistent protection performance with robust construction designed for long service life in demanding environments.
