Cutler QLP-1 Main Breaker Panelboard Assembly

The Cutler QLP-1 Main Breaker Panelboard Assembly is a 60 A, 240 V, three‑phase, four‑wire panelboard with a built‑in main breaker, designed to distribute electrical power in commercial or light industrial settings. Also known as Cutler Hammer QLP-1, it provides 42 spaces for branch circuit breakers, enabling scalable protection and organized circuit layout within a single enclosure. With an 18 kA short‑circuit rating, it offers upstream fault protection while consolidating control in a central disconnect point for a 240 V three‑phase distribution system. The 42‑space configuration supports a substantial number of branch circuits, making it suitable for facilities that require centralized protection and efficient maintenance, while the 240 V three‑phase operation aligns with common industrial power systems.
