FAQs
DH426SNRKLCR is designed as a Series K compatible, four-pole, 600A safety switch with a NEMA 3R enclosure, making it suitable to retrofit into many Eaton-based installations. When planning mounting, verify vertical clearance for the 74.34 in height and allow space for the 32.87 in depth and 16.1 in width. Use Cam-Lok connectors for quick wiring and ensure proper neutral switching per the fusible configuration. Confirm panel interlock and control wiring matches your existing control scheme to prevent misoperations.
The DH426SNRKLCR features a NEMA 3R enclosure designed for outdoor and damp-location resilience. This enclosure protects internal contacts and wiring from precipitation, dust, and temperature variations, reducing field maintenance. The UL Listed certification further ensures compliance with safety standards in exposed environments. For outdoor installations, consider additional rain shielding where extreme weather is expected, and ensure proper mounting hardware to resist wind loads.
Fusible with switched neutral provides controlled fault isolation and safer neutral disconnection during maintenance. This arrangement helps maintain proper circuit protection coordination and reduces the risk of neutral-related faults during servicing. From a maintenance perspective, it simplifies troubleshooting by clearly delineating live and neutral paths and supports orderly shutdowns for motor loads and feeders, contributing to predictable downtime and safer work conditions.
The key certification included is UL Listed, which confirms adherence to recognized safety standards for electrical devices. This is critical for regulatory compliance, audits, and end-user safety programs. While not a CE or IP rating in the data provided, the UL Listing combined with the NEMA 3R enclosure offers a strong assurance of ruggedness and safety for industrial facilities, especially where outdoor exposure or harsh environments are involved.
The DH426SNRKLCR delivers measurable ROI through reduced downtime, faster installations, and longer service intervals due to a robust, weather-resistant enclosure and secure Cam-Lok wiring. The four-pole 600A design supports large, reliable isolations, minimizing arc-flash exposure during maintenance. In turn, facilities can achieve lower labor costs, fewer unexpected outages, and better asset protection for high-value equipment.
