FAQs
Installers should plan for the panelboard’s 23.9 in depth and 7.3 in width within a suitably sized interior cabinet. Use the three-pole copper connectors for all phase terminations, ensuring solid, low-impedance connections. Follow UL 67 guidelines, secure the unit to the internal rack or backplane, and route wiring via the provided pathways to minimize heat buildup and maintenance access issues.
The PRXKPRL4X336 carries UL 67 certification, confirming safety for interior panelboard assemblies. This helps simplify regulatory approvals for many North American projects and supports ongoing compliance during audits. For regions outside the US, verify regional standards such as CE or IP ratings as applicable to your site requirements.
Yes. The PRXKPRL4X336 is designed to integrate with Eaton’s Pow-R-Xpress stocking program, which supports faster procurement and project readiness. This compatibility helps reduce lead times, streamline component sourcing for interior panelboards, and simplify project costing for OEMs and facilities teams.
This panelboard is best suited for interior power distribution in control cabinets and machine rooms. Its three-pole copper connectors and compact form factor make it ideal for space-constrained enclosures, modular automation architectures, and retrofit projects where reliable, UL 67‑listed interior panel distribution is required for low-voltage systems.
Expect improved maintenance predictability from a robust copper terminations design and easy access for routine checks. The compact size reduces cabinet footprint and wiring complexity, lowering labor costs during installs and upgrades. Over the product lifecycle, this translates to shorter downtime, fewer corrective actions, and a lower total cost of ownership for interior distribution in automation environments.
