Description
Built to handle complex commercial loads, this 400A PowerPacT L-Frame breaker incorporates a MicroLogic 3.3 electronic trip unit. This technology provides true RMS sensing and adjustable settings for precise system coordination. The factory-installed I-Line mounting assembly facilitates rapid insertion into Square D I-Line panelboards, effectively replacing older LA36400 thermal-magnetic units. Rated for 100kA at 480VAC, this current-limiting device minimizes let-through energy during faults.
