FAQs
The PRL4X3890B18C1S is designed for seamless integration with Eaton's Pow-R-Xpress interior family and compatible 68.75 in L x 22 in W x 8 in H footprints. It uses top-feed copper bus and standard 800A, 208/120V 3P 4W configuration, enabling plug-and-play assembly with existing interior components. Leverage the same wiring layouts and field installation practices used for other PRL4X interiors to reduce engineering time.
Plan for 208/120V three-phase operation with a robust 800A amperage rating and 18 circuits. The interior panelboard uses copper bus, top-feed configuration, and supports a 68.75 in L x 22 in W x 8 in H footprint. It is UL 67 certified, aligning with standard safety requirements for control panels and interior electrical rooms.
UL 67 listing confirms suitability for panelboard interiors in many control and switchgear environments. While it supports compliance and safety validation, always verify project-specific requirements, including environmental conditions, enclosure ratings, and local codes, to ensure full acceptance in your facility. The PRL4X3890B18C1S provides a solid baseline for these assessments.
Key considerations include using the copper bus for improved efficiency and heat management, leveraging top-feed design to simplify wiring, and the compact interior footprint to optimize space. UL 67 compliance reduces risk of non-conformance. The availability of Pow-R-Xpress reference guides accelerates configuration, lowering engineering time and on-site labor costs.
Technical resources include the Pow-R-Xpress quick selector reference guides and program brochures listed in Eaton’s downloads. These documents guide model selection, circuit routing, and configuration within the PRL4X interior family, helping shorten design cycles and support accurate field implementation.
