Eaton PRL2X3400B42C Pow-R-Xpress Panelboard - UL 67
Part Number: PRL2X3400B42C
Quick Summary
The Eaton PRL2X3400B42C Pow-R-Xpress panelboard is a 480/277V interior distribution solution for three-phase, four-wire systems used in commercial and light industrial facilities. Upgrading power distribution often introduces space constraints, downtime, and complex wiring challenges that slow project timelines. This panelboard carries UL 67 certification and is designed with a copper bus to ensure low impedance and reliable fault clearing, while delivering up to 400A and 42 circuits in a long interior enclosure. Its compact, high-density footprint translates to faster installations and lower total cost of ownership, making it a practical choice for engineering teams seeking scalable, compliant distribution with proven performance.

FAQs
The PRL2X3400B42C is designed for interior 480/277V three-phase, four-wire distribution in commercial and light industrial facilities. It accommodates up to 42 circuits within a 72 inch long interior enclosure, using copper bus for reliable current paths. This makes it suitable for retrofit projects and new builds where space and wiring efficiency matter.
A 400A amperage rating provides ample headroom for typical commercial loads and short-term peak demand. It supports high-density distribution while maintaining voltage stability and protection. For project planning, this means fewer mid-project panel upgrades and simpler feeders, reducing both risk and total installed cost.
Yes. The panelboard is an interior 480/277V, three-phase, four-wire solution geared toward commercial and light industrial environments, including manufacturing. Its copper bus and UL 67 certification contribute to safe, efficient operation in demanding settings, with 42 circuit capability to handle multiple feeders and branch circuits.
The PRL2X3400B42C is part of Eaton’s Pow-R-Xpress stocking program, designed to streamline procurement with predictable lead times. This helps project teams reduce downtime during installation and simplifies scheduling, especially for mid- to large-scale electrical builds.
The panelboard carries UL 67 certification, indicating compliance with recognized safety standards for panelboards. This certification supports regulatory acceptance, insurer confidence, and safer operation in electrical rooms.
