Eaton PRL4X3173LB0C2 Panelboard - UL 67, 1200A
Part Number: PRL4X3173LB0C2
Quick Summary
PRL4X3173LB0C2 Eaton Pow-R-Xpress panelboard is a high-capacity power distribution solution for 480/277V, three-phase systems. Facilities often face space constraints, downtime during upgrades, and compliance hurdles when expanding feeders; this interior panelboard is designed to minimize those challenges with a robust, bottom-feed design and a 1200A rating. UL 67 certification pairing with copper bus construction provides durable fault protection and reliable performance in harsh industrial environments. By simplifying installation and offering clear field upgrade paths, this solution supports faster commissioning, safer maintenance, and longer service life. In addition, the Pow-R-Xpress ecosystem assets and data sheets help engineers optimize stocking and interface with existing switchgear.

FAQs
Yes. The PRL4X3173LB0C2 is designed for 480/277V, three-phase systems with a bottom-feed configuration (MLO). It is compatible with common Eaton Pow-R-Xpress panelboard ecosystems and supports straightforward field wiring. When planning retrofit projects, verify bus material (copper), amperage rating (1200A), and the MTBF expectations to ensure seamless integration with existing breakers and feeders.
Key specs include a 1200A amperage rating, 480/277V operation, three-phase four-wire configuration, copper bus, and UL 67 certification. This combination minimizes voltage drop, reduces heat rise, and improves long-term reliability. In practice, these attributes support higher load capacity with lower energy losses, enabling more efficient distribution to motors, lighting, and process equipment.
Yes. The 1200A rating, copper bus, and UL 67 certification make it appropriate for critical-load environments where reliability and fault protection are essential. The bottom-feed MLO design simplifies wiring and maintenance, helping minimize downtime during routine changes or expansions common in data centers and manufacturing floors.
This panelboard carries UL 67 certification, which confirms suitability for interior electrical distribution. Compliance with UL standards supports safety, reduces audit risks, and aligns with typical building codes for commercial and light-industrial installations. Always verify local code adoption and ensure compatible accessories and breakers are used with the PRLX4 family.
The Pow-R-Xpress stocking program streamlines procurement with pre-approved configurations and readily available spares, reducing lead times and project delays. ROI benefits come from faster commissioning, lower maintenance overhead thanks to durable copper bus, and reduced downtime during future expansions since the panelboard is designed for straightforward field upgrades and compatibility with common Eaton components.
