FAQs
DH224FRK is a two-pole, two-wire safety switch rated at 200A and 240V. It accommodates large conductors up to #6-250 kcmil Cu/Al, enabling straightforward feeder connections. Its NEMA 3R enclosure and painted galvanized steel construction support indoor and outdoor installations, while the enhanced visible blade aids quick status checks during maintenance. For panel integration, ensure clearance for a 30 inch length footprint and plan wiring routing to minimize voltage drop and thermal buildup.
Class H fuse provision defines the fuse type used within the heavy duty fusible switch, paired with time-delay characteristics suitable for motor starting surges. This enables proper coordination with upstream protective devices and stable fault clearing without nuisance trips. It’s ideal for applications requiring controlled inrush management and predictable protection for 1-3 phase motor feeders at 240V.
The DH224FRK excels in motor-driven applications such as conveyors, packaging lines, and process equipment where robust short-circuit protection and fast fault isolation reduce downtime. Its NEMA 3R enclosure supports outdoor or damp environments, and the 200A rating suits mid-scale feeders. It’s particularly valuable during plant upgrades or retrofits where reliability, compliance, and ease of maintenance are priorities.
Yes, the DH224FRK carries UL Listed certification, providing recognized electrical safety compliance. Its NEMA 3R enclosure adds weather and corrosion protection suitable for many industrial environments. While it offers robust protection for general industrial use, always verify local electrical codes and any industry-specific standards before deployment.
The DH224FRK delivers value through reduced downtime from quick fault isolation and durable galvanneal enclosure protection. The 1-year warranty (or 18 months from shipment) supports initial ownership costs, and the unit’s compatibility with common conductors and standard fuses simplifies maintenance and spares management. For total cost of ownership, consider installation efficiency, energy protection, and extended panel reliability.
