Square D LE36225LI I-Line Molded Case Circuit Breaker

The Square D LE36225LI is a 225 A, 600 V, 3‑pole molded‑case circuit breaker designed for I‑Line plug‑in mounting in compatible Square D panelboards. It uses a Micrologic electronic trip unit (non‑interchangeable) that provides Long‑Time and Instantaneous trip functions for precise three‑phase protection. With an interrupting rating up to 65 kA at 480 V, it handles high‑fault currents typical in industrial feeders while delivering fast fault isolation. This LE model is part of Square D’s I‑Line family, engineered for compact panelboard installations that require reliable protection in 600 V class systems. The unit is intended for use on three‑phase circuits and is well suited for commercial and light‑industrial distributions such as manufacturing lines, processing equipment, and critical building services where consistent protection and coordination are essential. As a non‑interchangeable trip unit in the LI family, it integrates with Square D LI‑style trip mechanisms and supports plug‑in mounting for streamlined installation and service in compatible panel infrastructures.
