Eaton Specification Sheet - DH165NWK
High-current isolation with 400 A capability and a fusible single-pole design ensures dependable de-energization of the DC circuit. This translates to faster maintenance windows and safer startup sequences for solar arrays and industrial power systems. Suitable for single-circuit DC distribution, the DH165NWK supports a clean, one-point disconnect in compact installations. Rugged enclosure with a NEMA 4X rating and 304 stainless steel construction resists moisture, dust, and corrosion, delivering reliable service in outdoor or wash-down environments. This minimizes weather-related nuisance trips and reduces maintenance cycles for outdoor substations and remote solar connections. The 600 VDC rating, fusible with neutral, and Class R protection provide clear fault isolation and safe energy removal, supporting compliant operation in industrial power distribution and solar DC systems. Large conductor capacity supports up to #2-600 kcmil copper or #1/0-750 kcmil aluminum conductors, enabling flexible wiring in diverse installations. Easy wiring and compatibility with a 1-circuit, 2-wire configuration simplify procurement and on-site installation, reducing total cost of ownership and accelerating project timelines. Warranty coverage (one year from installation or 18 months from shipment) adds predictable maintenance budgeting and long-term reliability for mission-critical DC applications.
