FAQs
The DH322NGK should be mounted in a NEMA 1 enclosure and wired as a three-pole, four-wire device with neutral. Use #14-2 AWG Cu/Al conductors and follow NEC guidelines for barrier protection in 230.62 compliant installations. Ensure proper clearances around the switch and accessible wiring for maintenance and safety checks.
The switch features a 60A amperage rating, 240V voltage rating, three poles, four wires, and a fusible Class H configuration with neutral. It supports HP ratings up to 15/10 hp depending on configuration, and uses #14-2 AWG Cu/Al conductors, making it suitable for 1P/3P applications in industrial settings.
Yes. With a 60A rating, 240V operation, three-pole design, and a fusible switch with neutral, it provides reliable isolation and fault protection for 3-phase motors in conveyors, pumps, and other automated equipment. The UL Listed status and NEMA 1 enclosure further enhance safety and reliability in typical production environments.
The DH322NGK is UL Listed and NEC 230.62 compliant for barrier protection. It comes in a NEMA 1 painted steel enclosure, aligning with common industrial safety and installation standards. These certifications simplify qualification during panel builds and reduce engineering overhead when pursuing code compliance.
Maintenance is straightforward due to a robust mechanical design and readily available Class H fuses for fusible protection. The 60A, 240V configuration supports predictable downtime and faster replacements, contributing to improved machine availability. A one-year warranty (with specific Eaton terms) further protects initial deployments and supports favorable total cost of ownership.
