FAQs
For installation, ensure adequate clearance in the electrical room and plan the 61 inch depth, 15 inch width, and 6 inch height to accommodate doors and space for wiring. Use the aluminum bus for lighter handling, verify 480/277V 3P4W connections, and confirm UL 67 and NEMA compliance requirements are met. Pre-assembly and factory wiring can reduce field errors and accelerate commissioning.
Yes. The PRL2X3400X42A is designed to align with Eaton's Pow-R-Xpress stocking program, enabling faster parts availability and simplified procurement. This compatibility helps shorten lead times, reduces project downtime, and supports easier maintenance planning during upgrades or expansions.
The panelboard is rated for 400A, supports 42 circuits, and operates at 480/277V. It carries UL 67 certification and is NEMA compliant, providing essential safety and regulatory alignment for interior power-distribution applications in commercial and light-industrial settings.
This interior panelboard is well-suited for commercial spaces and light-industrial environments that require reliable 3-phase, 4-wire distribution. It supports tight space installations and projects needing scalable capacity for future load growth, making it ideal for manufacturing lines, data centers, and large office facilities.
Maintenance benefits include lighter handling due to aluminum bus, simpler access to 42 circuits, and a compact footprint that reduces routine inspection time. ROI is accelerated by faster procurement through Pow-R-Xpress, reduced field wiring errors, and lower downtime during upgrades, contributing to lower total cost of ownership over the system’s life.
