Schneider Electric Powerpact LJA36250CU33X is a 100% rated molded case circuit breaker designed for primary overcurrent protection in industrial power distribution systems. This three-pole, 600V AC unit delivers a continuous current rating of 250A with a solid-state LSI trip unit providing long-time, short-time, and instantaneous protection functions. The breaker features an L Frame size, I-Line style plug-in connection with terminal lugs (AL400L61K3), and accepts copper wire from AWG 2 to 600 kcmil or aluminum wire from AWG 2 to 500 kcmil, measuring 13.4 in x 5.5 in x 4.3 in and weighing 17.311 lb. It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, with an interrupting capacity of 65 kA at 480V AC and an operating temperature range of -2°C to 70°C. This circuit breaker is suited for main or feeder protection in switchboards, panelboards, and motor control centers requiring high fault current withstand and adjustable trip settings.
