FAQs
The R3CPL136 is an outdoor-rated, main lug only loadcenter with 42 spaces designed for three-phase 120/208 V systems. Install on a stable, level surface with proper clearance, secure the enclosure to a fixed base, and verify NEMA 3R weather protection seals. Follow manufacturer guidelines in the Eaton BR ecosystem for wiring, grounding, and labeling to ensure safe, compliant operation.
Yes. The R3CPL136 supports 120/208 V three-phase power and is rated for 125 A. This makes it suitable for mid-size outdoor installations requiring robust, mains-distribution capability with a dense 42-space configuration to accommodate multiple circuits.
This unit carries CSA Std. C22.2 No. 29 certification, signaling compliance with recognized safety standards. It uses a NEMA 3R enclosure, which denotes weather resistance suitable for outdoor use, protecting contents from rain, sleet, and corrosion. Together, these ratings support regulatory compliance and safe operation in outdoor industrial environments.
The R3CPL136 is a non-combination, main lug only design with 42 spaces indicating a fixed circuit capacity. While it supports 42 slots now, future expansion typically involves upgrading to a larger enclosure or adding compatible BR accessories to reconfigure the distribution, ensuring continuity with Eaton’s BR family for consistent installation practices.
Maintenance for the R3CPL136 is focused on routine inspection of connections, bus bars, and enclosure seals to prevent corrosion and ensure proper operation. Warranty information is provided by Eaton; users can refer to the Eaton BR warranty document issued June 2024 for terms and coverage, and should consult the official specification sheet for recommended service intervals and component life expectations.
