FAQs
When installing the R1124 HDD, plan for surface-mount mounting with the supplied 5/16 inch mounting holes and ensure adequate clearance for the 57 in width and 22 in height. Verify lug compatibility (#4 - 600 MCM line lugs and 5/16 inch load lugs) and confirm space for (2) 1/0-250 MCM cables. The unit’s UL Listed status supports compliance audits and procurement standards.
A 600 A bus rating accommodates substantial conductor loads, while a 10 kAIC interrupt rating provides protection against high fault currents. This combination improves protection coordination with downstream devices and reduces the need for multiple smaller cabinets, simplifying design and installation in mid-to-large industrial feeders.
Yes. The R1124 HDD uses a galvanized steel enclosure with ANSI 61 gray paint and a NEMA 3R rating, making it suitable for outdoor or semi-exposed environments where rain, dust, and incidental moisture may be present, while maintaining electrical safety and reliability.
The cabinet is designed for line lugs sized #4 - 600 MCM and load lugs sized 5/16 inch, supporting heavy feeders. It also accommodates dual conductor entries up to 1/0-250 MCM, providing flexibility for diverse cable configurations and simplifying field terminations.
The R1124 HDD delivers faster installation, reduced wiring complexity, and improved fault protection, all in a single enclosure. Its durable materials and UL/NEMA-compliant design support higher uptime, easier maintenance, and scalable distribution for expanding 3Ø/4W systems in manufacturing or processing plants.
