FAQs
For proper installation, follow Eaton wiring diagrams and ensure the device is mounted in a clean, dry location. Use the three-pole, four-wire configuration with the neutral, observe correct polarity, and consult the catalog notes for 2-pole applications (use outside poles of a 3-pole switch). If outdoor use is anticipated, plan for field modification to NEMA 3R rainproof by opening the drain hole as factory specified.
The DH362NDKW is rated for 60 A with a maximum HP of 20, 25/30, and up to 50 hp for 1/3PH at 480 to 600 V. It is a three-pole, fusible switch with neutral, designed for up to 600 V systems. This makes it suitable for motors, pumps, and line feeders in mid-size industrial applications while maintaining strict overcurrent protection and fault isolation.
Yes, in indoor or semi-outdoor settings the enclosure supports NEMA 12 protection; field modification can achieve NEMA 3R rainproofing by enabling a factory drain hole. This provides a practical path to weather-ready protection without replacing the entire switch, reducing installation time and long-term operating costs.
The DH362NDKW is UL Listed, confirming recognized safety performance. Its enclosure ratings (NEMA 12/3R) indicate suitable protection levels for indoor and outdoor or semi-exposed installations. This combination supports compliance in most industrial facilities and aligns with common electrical protection and circuit-control requirements.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first. Routine maintenance involves periodic inspection of fuses, connections, and enclosure seals, with easy fuse replacement and a modular design that minimizes downtime during servicing, contributing to improved overall ROI through reduced outage duration.
