Eaton Specification Sheet - DH225NRKLCR
Feature → Business Impact → Application: The DH225NRKLCR delivers a two-pole 400A, 240V rating within a Series K framework, optimizing power isolation for large industrial feeders and switchgear installations. This translates to predictable fault-clearing performance and reduced risk during maintenance, supporting uptime in manufacturing lines and water/wastewater facilities where reliability matters. Feature → Cam-Lok reverse pin → Application: Cam-Lok reverse pin connectors enable quick, secure field wiring and simple reconfiguration, decreasing installation time and limiting misconnections in crowded electrical rooms or outdoor switchyards. Feature → Fusible with solid neutral → Application: Fusible with solid neutral provides controlled interruption and stable neutral reference, improving arc-quenching behavior and voltage stability in heavy-duty drivelines. Feature → NEMA 3R enclosure → Application: Rugged enclosure protection enables reliable outdoor and harsh-environment operation, aligning with industrial site standards and reducing enclosure-related failures. Feature → UL Listed → Application: Ul Listed certification supports regulatory compliance and documentation for procurement, audits, and maintenance planning across automotive, food & beverage, and metals processing sectors. Warranty: A one-year warranty from installation or eighteen months from shipment reduces ownership risk and supports long-term total cost of ownership considerations.

FAQs
Yes. The DH225NRKLCR is designed around Eaton’s Series K platform and uses a NEMA 3R enclosure, making it suitable for outdoor and harsh environments. It supports 400A, two-pole operation at 240V with fusible with solid neutral, facilitating straightforward integration with existing low-voltage distribution assemblies and standard enclosure footprints.
The unit provides 400A amperage, 240V voltage, and a two-pole configuration. This setup delivers robust fault isolation for medium-to-large industrial feeders, improves arc quenching behavior, and maintains a solid neutral for voltage stability during switching events, helping to minimize downtime and protect downstream equipment.
Industries with demanding power-distribution needs—such as manufacturing, mining, water treatment, and heavy equipment uptime-critical environments—benefit from this switch. Its Cam-Lok reverse pin, UL Listed certification, NEMA 3R protection, and Series K interoperability support reliable outdoor installations, safe maintenance, and compliance with safety standards.
The DH225NRKLCR carries UL Listed certification and is rated for NEMA 3R enclosures, ensuring compliance for outdoor and rugged installations. The protection features, including fusible with solid neutral and Cam-Lok connections, provide predictable performance under fault conditions while supporting regulatory documentation and audits.
Selecting this switch reduces maintenance risk through rugged construction, reliable isolation, and a long service life on Series K platforms. The included one-year warranty (or 18 months from shipment) lowers ownership risk, while quicker installation with Cam-Lok reverse pin connections minimizes labor costs and downtime, delivering a favorable total cost of ownership over the equipment lifecycle.
