FAQs
The PRL2X3400B42A is designed for interior power distribution at 480/277V, 3-phase, 4-wire configurations. It supports a 72 inch long enclosure with 42 circuits, incorporating MCBs and SFBs for streamlined commissioning. This panel is UL 67 certified and uses aluminum bus, making it suitable for industrial facilities requiring high circuit density in a compact footprint.
The panelboard provides a 400A amperage rating, suitable for main feeders and sub-feed applications in moderate-to-heavy industrial environments. It uses aluminum bus material, which offers good strength-to-weight characteristics, reduced weight for handling during installation, and reliable electrical performance under vibration and thermal cycling.
Yes. The PRL2X3400B42A carries UL 67 certification, indicating compliance with recognized standards for panelboards. This certification supports safe operation, reduces regulatory risk during audits, and helps ensure code-compliant installation in commercial and industrial facilities.
Pow-R-Xpress PRL2X3400B42A is an interior, pre-engineered panelboard with integrated MCBs and SFBs, designed to minimize field wiring and simplify mounting. The combination of a ready-to-install interior unit, 42 circuits, and a 72 inch length reduces labor and commissioning time, delivering faster project turnover and tighter installation schedules.
Typical applications include industrial facilities with multiple machine clusters, packaging lines, and process equipment requiring high circuit density in a compact enclosure. The 480/277V 3P 4W configuration, 400A rating, and aluminum bus support reliable power distribution for manufacturing plants, data processing areas, and control rooms while enabling scalable expansion as loads grow.
