Square D LGA36600U33X I-Line Circuit Breaker

Square D LGA36600U33X is a PowerPact L-frame I-Line molded‑case circuit breaker rated for 600 A, 3 poles, at 600 V AC, designed for heavy‑duty feeder protection in industrial power distribution and motor‑control applications where compact, plug‑in protection is required. This 3‑pole unit employs a non‑interchangeable MicroLogic 3.3S electronic trip unit for precise long‑time, short‑time, and instantaneous protection and uses an I‑Line plug‑on mechanism for straightforward integration into PowerPact L enclosures. Interrupting capacities of 65 kA at 240 V, 35 kA at 480 V, and 18 kA at 600 V provide robust short‑circuit protection across common distribution voltages, and the device is UL-listed as part of Square D/Schneider Electric’s PowerPact L family. Commonly used in industrial service feeders, MCCs, and distribution panels, the LGA36600U33X delivers reliable protection within PowerPact L‑series systems and I‑Line bus configurations for industrial facilities requiring rugged, field‑serviceable current protection.
