FAQs
The Eaton BR main lug loadcenter is designed for surface mounting in indoor environments and uses a standard three-phase configuration. Its 42-space design supports versatile wiring schemes, while the aluminum bus reduces weight during site handling. Ensure enclosure dimensions align with your wall space and confirm clearances per NEC requirements before mounting.
Key specs include a 600 A amperage rating, aluminum bus material, 42 circuits and 42 spaces, and three-phase operation. The enclosure is NEMA 1, with factory integrated surge protection available. The Catalog Number is 3BR4242L600S, and it is UL Listed (E52977) and UL 67, which supports reliable, compliant electrical distribution.
Yes. The 600 A main lug design with 42 circuits provides scalable three-phase distribution for mid-size manufacturing lines, machine rooms, and data-center-adjacent infrastructure. Aluminum bus supports durable performance in industrial environments, while the NEMA 1 enclosure protects against dust and incidental moisture in indoor spaces.
This unit carries UL Listed certification (E52977) and meets UL 67 standards, with a NEMA 1 enclosure rating. These certifications validate electrical safety, construction integrity, and suitability for indoor service conditions, helping meet regulatory and commissioning requirements in many facilities.
The 10-year limited warranty reduces long-term ownership risk, while factory integrated surge protection minimizes external hardware and potential downtime. Lower weight from aluminum bus simplifies handling, and the robust three-phase distribution reduces panel count in scalable projects, contributing to faster commissioning and lower lifecycle costs.
