FAQs
When planning installation, account for the 79 inch length, 8.5 inch width, and 3.75 inch height to ensure enclosure compatibility. The panelboard supports 3P4W 480/277V with a 400A rating and 42 circuit density, which impacts bus routing, feeder sizing, and space allocation. Use the dual SFB provision to accommodate future circuit additions without major rearrangements, and verify NEMA-compliant enclosure requirements prior to mounting.
Yes. The PRL2X3400X42CD is UL 67 certified and NEMA compliant, which aligns with common safety and installation standards for low-voltage panelboards. These certifications support regulatory approvals, simplify inspections, and provide confidence for utility coordination and facility commissioning. No misleading certifications are claimed beyond what is specified for this model.
This panelboard excels in plants, warehouses, data centers, and commercial facilities needing dense, reliable power distribution from 480/277V systems. Its 400A rating and 42 circuits enable centralized control of multiple loads, while copper bus ensures improved efficiency and durability. The interior design supports quick wiring, phased expansions, and compliance-driven installations typical in manufacturing environments.
The dual SFB (short circuit and fault protection) provision allows additional circuits to be wired with minimal rework, enabling phased capacity expansion and streamlined maintenance. This reduces downtime during upgrades and provides a predictable path for future load growth, which is especially valuable in facilities anticipating load increases or process changes over time.
Key specs include a 400A amperage rating, 480/277V four-wire three-phase configuration (3P4W), 42 circuits, and copper bus material. Physical dimensions are 79 in length, 8.5 in width, and 3.75 in height with an approximate weight of 184.54 lb. The unit is UL 67 certified and NEMA compliant, designed for interior installation with high-density circuit provisioning.
