FAQs
Wiring DH262NRK begins by connecting the incoming line to the line terminals of the switch, the load to the load terminals, and placing the neutral conductor through the fusible path as required by the fusible-with-neutral configuration. Attach a solid, properly rated ground. Verify 60 A amperage, correct Class H fuse, and 600 V rating before energizing. Follow NEC and UL guidelines for safe commissioning.
DH262NRK is rated for 600 V and supports up to 60 A. The HP rating allows up to 20–25 hp for single-phase operation at 480/600 V (TD/600 Vdc). This enables reliable protection for small to mid-size motors, ensuring proper fuse protection, controlled startup, and protection against overloads or short circuits in motor circuits within those limits.
Yes. The DH262NRK uses a NEMA 3R enclosure made from painted galvanized steel, providing outdoor-ready protection against rain, dust, and incidental moisture. This makes it suitable for outdoor panels, equipment rooms, and semi-exposed installations where weather resistance is a requirement, reducing the need for additional housing or enclosure upgrades.
The DH262NRK is UL Listed and NEC barrier compliant, with a NEMA 3R enclosure rating. It supports NEC 230.62 barrier requirements for safe installation, and its 600 V rating aligns with typical industrial motor protections. These certifications simplify procurement, ensure regulatory alignment, and support safer, code-compliant control panels.
Maintenance revolves around fuse replacement and periodic inspection of enclosure integrity and wiring. The unit’s robust NEMA 3R enclosure and Class H fuse design reduce downtime and demand fewer field repairs. Eaton’s warranty and standard parts availability help manage lifecycle costs, with straightforward fuse replacements and predictable service intervals to maximize uptime.
