Square D PGA36100U43A is a Schneider Electric Powerpact molded case circuit breaker designed for primary overcurrent protection in industrial power distribution systems. This 3-pole unit is rated for 1000A at 600VAC with a 35kA interrupting capacity at 480VAC, utilizing solid-state LSI (Long-Time, Short-Time, and Instantaneous) trip functions for precise protection coordination. The breaker measures 16.16 in x 8.27 in x 8.05 in (410.46 mm x 210.06 mm x 204.47 mm) and weighs 32 lb, featuring an I-Line style plug-in connection and accepting 4 x AWG 3/0 to 500 kcmil aluminum/copper conductors. It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, with an operating temperature range of -13°F to 158°F (-25°C to 70°C). Typical applications include main or feeder protection in switchboards, panelboards, and motor control centers within commercial and industrial facilities.
