FAQs
For retrofit or new panel builds, plan for a two-pole, fusible switch mounted within a NEMA 3R enclosure. Ensure adequate clearance for 16.5 inch depth, 8.5 inch height, and 9.5 inch width, and verify compatibility with 60A fuses and 240V circuits. Use proper disconnect timing and verify conductor gauge (#14-#2 Cu/Al) matches the fuse class and wiring.
The device is rated 60A with a 240V nominal voltage, two poles, and fuse configuration that is fusible without neutral. It supports motor HP ratings up to 15 hp (1–3 phase) with standard fuse/time-delay options, enabling selective protection and controlled inrush management. This combination improves protection coordination and minimizes unnecessary downtime from nuisance trips.
Yes. The enclosure is NEMA 3R rated and constructed from painted galvanized steel, providing weather resistance for outdoor and semi-indoor installations. UL Listed certification further confirms compliance with safety standards, making it appropriate for harsh environments while maintaining enclosure integrity and electrical safety.
The DH222FRK carries UL Listed certification and is housed in a NEMA 3R enclosure, signaling readiness for industrial electrical protection requirements. This combination supports compliance with common electrical codes for indoor and outdoor equipment, simplifies procurement and inspection processes, and helps ensure maintenance teams meet regulatory expectations during audits.
With a 60A, 240V rating and robust NEMA 3R enclosure, the DH222FRK minimizes unplanned outages by providing reliable fault interruption and durable protection for motors and feeders. The UL Listed certification, compact footprint, and straightforward installation reduce maintenance costs and spare-parts inventory, delivering measurable ROI through improved uptime, safety, and total cost of ownership.
