Industrial 4000A-Main-Breaker-Panelboard-480V-277V-208V-120V-GFI-ARC-FLASH Panelboard

Industrial 4000A main-breaker panelboard built for heavy-duty electrical distribution in commercial and industrial facilities, featuring a 4000-amp main breaker and the ability to feed circuits at 480V, 277V, 208V, and 120V across dedicated bus configurations. Designed to consolidate high-current feeders and mixed-voltage branches within a single enclosure, it simplifies power-system topology by enabling centralized protection coordination and reducing the need for multiple panels in facilities with diverse loads. With GFI protection incorporated for applicable circuits, it supports ground-fault interrupt functionality to safeguard personnel and equipment where faults can occur. Typical installations include large-scale manufacturing facilities, data centers, and other sizable commercial environments that require robust main protection and the flexibility to distribute multiple voltages from one panelboard. The combination of a 4000-amp main rating and multi-voltage capability supports scalable distribution for evolving electrical layouts in growing facilities.
