FAQs
The DH265FRKV is rated for 600 V systems and comes in a NEMA 3R enclosure, suitable for both indoor and outdoor installations. Its two-pole, two-wire configuration and Class H fuse provision support reliable circuit protection for high-power motors and feeders while meeting environmental protection standards.
UL Listing confirms the device meets recognized safety standards, while NEC 230.62 barrier compliance ensures proper clearance and safe operation in electrical installations. Together, these certifications streamline audits, improve safety, and simplify procurement for regulated facilities.
A 400 A rating enables the switch to safely interrupt large fault currents and protect downstream equipment. Combined with 50 HP at 250 Vdc capability, it supports robust protection for high-load motors and drives, reducing risk of thermal overload and unplanned downtime.
Yes. The NEMA 3R enclosure, painted galvanized steel, provides weather resistance and corrosion protection suitable for outdoor or semi-exposed locations. This makes it a reliable choice for substations, outdoor panels, and protected plant perimeters.
The HDSS designation signals rugged construction designed for durability and ease of service. Benefits include longer service intervals, lower maintenance costs, and reduced downtime during routine servicing. Pairing UL Listed protection with a robust enclosure also supports predictable lifecycle planning and faster commissioning.
