When dependable power is critical in outdoor or partially sheltered settings, DEI Power Solutions delivers. Our 1200 AMP NEMA 3R panelboard is engineered for consistent performance in demanding environments, backed by UL 891 certification and fully customizable to fit your operational requirements.
With reliable performance and precision engineering, we ensure your electrical systems are supported with the exact power capacity you need. We offer complete switchgear solutions — 600A, 800A, 1200A, 1600A, 2000A, 2500A, 3000A, and 4000A.
NEMA 3R enclosures are designed to protect internal electrical components from rain, sleet, and snow, making them a go-to choice for outdoor power distribution. By combining this durable weatherproof design with a 1200 AMP capacity, we provide a robust solution for medium- to high-load applications.
NEMA 3R enclosures are best suited for:
Ideal for high-capacity utility yards and electrical distribution hubs.
Perfect for exterior plant and process power distribution points.
Designed for pad-mounted or rooftop power applications.
Supports solar farms, wind generation, and other clean energy projects.
Every 1200 AMP NEMA 3R panelboard system we build is tailored to your project’s exact needs. From breaker configuration and voltage rating to enclosure design, our engineering process ensures compatibility with your electrical infrastructure while meeting UL 891, NEC, and CSA compliance standards.
Rugged design for challenging conditions
Built to manage significant industrial and commercial loads, our systems deliver reliable service without compromise. The NEMA 3R-rated enclosure shields components from rain, airborne debris, and corrosion, ensuring stable operation in harsh outdoor environments.
Custom-built for exact site compatibility
We fabricate every unit to match your site’s specifications, minimizing costly on-site modifications and installation delays. By using CAD modeling, precision busbar fabrication, and in-house CNC machining, we ensure consistent quality and fully compliant operation from the start.
Our 1200 AMP NEMA 3R systems are engineered for steady output, extended service life, and ease of maintenance — keeping your operations powered without unnecessary downtime.
What sets our systems apart:
Every enclosure and busbar is manufactured to exact specifications for fit and function.
NEMA 3R-rated to resist water, ice, and airborne contaminants.
Simplified layout for faster inspections and servicing.
Meets UL 891, NEC, and CSA standards in every build.
We don’t just assemble components — we engineer every system from the ground up for performance, safety, and longevity. With full in-house manufacturing, we control every stage of production, ensuring you get precisely the gear you ordered, on time, and built for decades of service.
“When your switchgear is mission-critical, you can’t afford to compromise. We build it right the first time.”
