Outdoor NEMA 3R enclosure provides weather-resistant protection for outdoor electrical distribution, reducing weather-related downtime and maintenance costs while enabling reliable service in exposed environments. The copper bus material offers superior conductivity and lower resistance, improving overall efficiency and reducing heat buildup during peak loads, which translates to longer equipment life and fewer replacement parts. With 42 spaces and 42 circuits, this loadcenter supports high-density power distribution and future expansion without reclosing to a new panel, enabling scalable motor control and feeder layouts for growing facilities. The 120/208 V three-phase configuration aligns with typical industrial equipment and drives, simplifying integration with existing controls and reducing wiring complexity for a faster, cleaner install. An interrupt rating of 35 kAIC enhances fault tolerance in higher-short-circuit scenarios, increasing system reliability and safety in critical applications.
