Eaton Specification Sheet - PRL1X1400X42CS
The PRL1X1400X42CS panelboard provides a robust 400 A amperage rating with 42 circuits in a compact 46 in by 15 in footprint, designed for 120/240 V service. This sizing enables scalable distribution without expanding room footprints, reducing capital costs and simplifying future expansion. Copper bus construction lowers impedance, improving fault clearance times and reducing voltage drop on critical feeders—translating to higher system reliability in manufacturing lines and data-processing environments. UL 67 certification and NEMA compliance deliver regulatory alignment and safer operation in demanding facilities, while the interior no-TFL design and easy wiring access streamline installation and maintenance. Compatibility with the Pow-R-Xpress stocking program supports faster procurement, standardization across sites, and reduced downtime during panel substitutions or upgrades. Overall, the solution combines performance, build quality, and supply-chain efficiency to lower total cost of ownership and improve uptime across facilities.

FAQs
The PRL1X1400X42CS interior panelboard measures 46 in long, 6 in high, and 15 in wide, with 42 circuits and a 400 A rating, making it suitable for standard electrical rooms. Its copper bus and 120/240 V, 1P 3W configuration facilitate straightforward wiring, leg-to-feeder connections, and minimal upfront rework. Its UL 67 certification and NEMA compliance further ease field approvals during retrofit projects.
Key specs include a 400 A amperage rating, 42 circuits, and 120/240 V input/output for 1P 3W service. The interior design supports a copper bus for lower impedance, and the enclosure dimensions (46 in L x 6 in H x 15 in W) influence feeder routing and cabinet integration. These details guide feeder allocation and shutdown sequencing in new installs or upgrades.
Yes. Its compact footprint, interior no-TFL design, and copper bus enable easier retrofits in constrained spaces. UL 67 and NEMA compliance help with regulatory approvals, while the Pow-R-Xpress stocking compatibility reduces lead times for replacement panels. This combination supports quick, minimally disruptive upgrades to machine controls and distribution networks.
The PRL1X1400X42CS carries UL 67 certification and is NEMA compliant, indicating adherence to key safety and performance standards for panelboards. These certifications help ensure safe operation, reliable performance under load, and easier acceptance by local authorities and electrical engineers during design reviews.
By delivering a high 400 A rating with 42 circuits in a compact enclosure, the unit reduces panel counts and space requirements, cutting installation and footprint costs. Copper bus improves electrical efficiency and reliability, lowering maintenance calls due to impedance-related issues. Fast stocking through Pow-R-Xpress further minimizes downtime and replacement expense during outages or upgrades.
