Square D by Schneider Electric LA363001021 PowerPact Molded Case Circuit Breaker is a 3‑pole, 300 A unit rated for 600 V AC, designed for use in industrial panels and distribution systems. It employs a thermal‑magnetic trip mechanism for overload and short‑circuit protection and includes a shunt‑trip option for remote actuation (120/240 V control). The breaker uses I‑Line line‑side plug‑in terminals with lug‑style load connections and belongs to the PowerPact LA family (L‑Frame). Short‑circuit interrupt ratings for this model vary by voltage, commonly cited as 22 kA at 240 VAC and 30 kA at 480 VAC, with a 600 V operating rating, making it suitable for feeders and motor circuits in demanding industrial environments.
