FAQs
The DH366UGKSNLC is a three-pole, unfused disconnect rated at 600A and 600V, designed to replace or supplement existing 600A switchgear. Plan for a Nepa-appropriate mounting footprint (32.87 in depth, 74.34 in height, 16.1 in width) and ensure proper lifting gear for its 370 lb weight. Cam-Lok connectors simplify wiring and reduce field torque, accelerating commissioning while preserving safe, code-compliant isolation during maintenance.
Key specs include 600A amperage rating, 600V voltage rating, three-pole configuration, unfused fuse configuration, and Series K construction with Cam-Lok connections. These factors provide robust fault isolation for large motors and feeders, enable quick, secure connections, and support reliable operation in demanding industrial environments while maintaining indoor NEMA 1 enclosure protection.
No. The DH366UGKSNLC features a NEMA 1 enclosure intended for indoor, dry locations. For outdoor or harsher environments, Eaton offers alternative enclosures and ratings; verify site conditions and consider enclosures rated for weather exposure and higher IP ratings to maintain protection and longevity in challenging environments.
The DH366UGKSNLC is UL Listed, reflecting compliance with recognized safety standards for electrical protection and control devices. It is designed for indoor use in NEMA 1 environments and aligns with Eaton’s reliability and quality standards, helping support regulatory requirements in industrial facilities.
The Cam-Lok connections and Series K design shorten wiring and maintenance time, reducing commissioning labor and arc exposure during service. The 1-year warranty (or 18 months from shipment) provides a defined support window, helping manage lifecycle costs. Overall, this switch can lower downtime costs and extend intervals between full-panel replacements in high-demand production lines.
