The Square D PGL36120U43A is a 3-pole molded case circuit breaker from the Powerpact family, designed for overcurrent protection in industrial power distribution systems. It is rated for 600V AC, 1200A continuous current, and provides solid-state LSI (Long-Time, Short-Time, and Instantaneous) trip functions for precise protection coordination. This feed-thru connection 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, with a temperature rating of -13 to 158 °F (-25 to 70 °C) and an AIC rating of 35 kA at 480V. It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, and is suitable for 3-phase systems with wire sizes from 4 x AWG 3/0 to 500 kcmil aluminum or copper. Typical applications include main or feeder protection in switchboards, panelboards, and industrial control panels.
