FAQs
The DH426SNRKLPR is a 600A, four-pole, fusible safety switch designed for straightforward integration with Eaton low-voltage protection hardware. Its Series K construction and Posi-Lok reverse pin minimize misalignment during mounting and commissioning, while the 32.87 in depth and 74.34 in height require compatible mounting space and support structures. Ensure that your enclosure footprint and wiring clearances meet NEC and local code requirements, and verify conductor sizing for 240V circuits to maintain safe, reliable operation.
Key compliance points include UL Listed certification for safety and performance, and NEMA 3R enclosure rating for outdoor or exposed indoor use. The unit is rated at 600A, 240V, with four poles and fusible with switched neutral, aligned with typical industrial protection standards. Warranty terms follow Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first, supporting long-term reliability assessments.
Yes. The DH426SNRKLPR uses a NEMA 3R enclosure, which is designed for outdoor use and protection against rain, sleet, and corrosion in many environments. Its heavy-duty construction and 600A, 240V rating are appropriate for demanding outdoor feeders and motor control centers, reducing weather-related maintenance while supporting robust safety isolation in harsh industrial locations.
Investing in the DH426SNRKLPR can reduce downtime and maintenance costs through its rugged build, reliable UL Listed safety and isolated wiring via fusible with switched neutral, and straightforward installation with Posi-Lok features. While initial space and weight (370 lb) considerations exist, long-term gains include fewer unscheduled outages, simplified spare-part planning within Eaton ecosystems, and a strong warranty framework to minimize lifecycle risk.
Posi-Lok reverse pin is designed to ensure correct engagement and locking orientation, preventing incorrect insertion or orientation during installation and maintenance. This reduces the risk of arcing or mis-wiring events, speeds up commissioning, and improves operator safety by providing a tactile, audible confirmation of proper alignment before switching.
