Pow-R-Line Xpert family overview
Feature → Business Impact → Application: The PRL3X3490B30C2 panelboard delivers a robust 400A amperage rating and a three-phase copper bus. This combination reduces voltage drop, improves fault tolerance, and supports larger main feeders, minimizing the need for additional subs and main-tie arrangements. It is well suited for commercial and light-industrial facilities distributing 480/277V across critical loads like lighting, HVAC, and equipment bays. Feature → Business Impact → Application: The top-feed design and interior assembly simplify wiring access and serviceability. Installers benefit from shorter wiring runs, fewer field adaptations, and quicker grounding and neutral termination. The panel is ideal for spaces with limited rear clearance or where rapid expansion is anticipated, enabling faster turnover on projects and easier future retrofit. Feature → Business Impact → Application: Copper bus material ensures high conductivity and long-term durability under frequent switching and fault conditions. This reduces energy losses and heat generation, contributing to lower energy costs and longer component life. Applications include emergency lighting circuits, critical power feeders, and facilities with tight reliability requirements. Feature → Business Impact → Application: UL 67 certification and NEMA compliance establish code-aligned safety for indoor power distribution. This helps facilities meet regulatory requirements, simplify inspections, and reduce risk of non-compliance penalties. Suitable for hospitals, data centers, commercial office environments, and manufacturing floors where dependable panelboard performance is essential. Feature → Business Impact → Application: The 30-circuit sub-chassis PD3 30CKT SUBCHS feature enables modular expansion without cabinet replacement. Operators can add circuits as loads grow, improving lifecycle value and reducing total cost of ownership. Combined with the 78 in length and 12 in width, it fits standard rack or corridor enclosures and supports straightforward retrofits in existing installations.
