FAQs
Plan for outdoor mounting with a compliant enclosure footprint (38.75 in height, 5 in width, 14.5 in depth). Ensure proper clearances for 42 spaces, three-phase 120/208 V wiring, and copper bus connections. Use appropriate conduit routing and secure mounting hardware to maintain weatherproof integrity in NEMA 3R environments.
The R3CPL130 is a main lug only panel, non-combination, designed to accept downstream BR-type breakers. It requires separate branch-circuit breakers to populate the 42 spaces. Verify listing and torque requirements per BR product guides to ensure compliant, safe operation with a maximum 125 A rating.
This enclosure carries CSA Std. C22.2 No. 29 certification and features a NEMA 3R outdoor enclosure. It supports three-phase 120/208 V operation with an interrupt rating of 35 kAIC, making it suitable for outdoor industrial and commercial environments.
Best for outdoor power distribution in industrial facilities, campuses, and commercial buildings requiring a weatherproof main-lug solution with substantial future expansion capacity (42 spaces) and reliable fault protection in three-phase systems.
Consult the Eaton warranty document for BR circuit breakers and the CSA certification scope. Routine inspections should verify enclosure integrity, bus connections, and seal integrity for outdoor use. The unit is designed for long-term reliability in harsh conditions, with documentation available for warranty terms and service guidance.
