FAQs
DH363NRKLPR is a three-pole, fusible with solid neutral device rated for 100A at 600V. It follows standard line/load wiring with a single-throw action. Verify panel compatibility with Eaton’s Series K footprint and torque specifications per the datasheet to ensure safe, code-compliant installation and optimal fault isolation performance.
Key ratings include 100A amperage, 600V voltage, three poles, and fusible with solid neutral. This configuration provides defined fault paths and stable neutral reference, supporting proper coordination with upstream protective devices. The device is UL Listed and designed for robust industrial service, reducing nuisance tripping and improving reliability in demanding environments.
Yes. The DH363NRKLPR uses a NEMA 3R enclosure, which is engineered for outdoor and moisture-prone installations. This enhances weather resistance and reduces maintenance intervals in exterior panels or damp plant locations, while maintaining safe isolation during maintenance and routine operation.
The product is UL Listed, indicating compliance with recognized safety standards for electrical protection equipment. The NEMA 3R enclosure rating further supports compliance for outdoor and indoor installations exposed to weather elements, aligning with common industry requirements for rugged control equipment.
Warranty follows Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. Regular inspection of fusible components and the Posi-Lok mechanism reduces misoperation and unplanned downtime, contributing to lower maintenance costs and a faster return on investment in steady-state operations.
