Eaton Specification Sheet - DH363UGKNLPR
Posi-Lok reverse pin provides secure engagement, reducing wiring errors and misalignment during installation and field service. This translates to fewer commissioning delays and safer lockout/tagout in industrial panels and MCCs. The rugged design supports long service life in harsh environments and simplifies troubleshooting during maintenance. Three-pole, 100A, 600V ratings deliver robust protection for typical motors and loads, resulting in fewer nuisance trips and more consistent startup in conveyors, pumps, and fans. The Series K construction offers durability for demanding applications, while the NEMA 1 indoor enclosure protects control components from dust and incidental contact in dry spaces, improving uptime and reducing field service calls. The unfused configuration provides flexible integration with external overcurrent protection during retrofit projects or new installations. Finally, the compact footprint and 85 lb weight facilitate planning, rigging, and transport within crowded industrial spaces, enabling rapid deployment.
