FAQs
Plan for the 32.87 in depth, 16.1 in width, and 74.34 in height footprint while accommodating a 370 lb weight. Utilize Cam-Lok connectors for rapid wiring, ensure clear access for neutral switching, and align with the Series K mounting pattern. Verify enclosure suitability (NEMA 3R) for the installation environment to maintain UL Listed compliance.
Its 600A amperage rating, 600V voltage rating, and three-pole configuration provide robust protection for large motors and feeders. The fusible with switched neutral design enables selective protection, while UL Listed certification supports regulatory compliance. This combination reduces protection coordination issues and helps prevent motor and drive damage in demanding industrial applications.
Yes. The DH366SNRKLC employs a NEMA 3R enclosure, which offers weather-resistant protection suitable for outdoor and harsh indoor environments. Combined with UL Listed certification, the switch is suitable for outdoor substations, equipment yards, and exposed service areas, helping maintain reliability and safety in variable conditions.
The product carries Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, rely on Cam-Lok connectivity to simplify field servicing, inspect neutral switching components during routine service, and use the Series K design to ensure consistent part replacement and uptime in high-demand environments.
Expect reduced commissioning time thanks to Quick Connect wiring and Cam-Lok assemblies, lower labor costs from faster installation, and improved uptime due to rugged NEMA 3R protection and UL Listed reliability. The 600A/600V rating also minimizes energy losses and protects critical machinery, contributing to a favorable return on investment over long-term operation.
