FAQs
The DH463URKSNLP is a four-pole, heavy-duty safety switch compatible with standard panel mounting footprints and Series K configurations. Plan for a secure mechanical fit, proper clearance for the NEMA 3R enclosure, and ensure wiring harnesses match the 100 A rating and 600 V system. Follow UL Listed installation guidelines to minimize handling risk and maximize reliability.
Yes. The DH463URKSNLP is designed as part of Eaton’s Series K family, offering seamless integration with compatible disconnects, feeders, and control components. For best results, match the same enclosure rating (NEMA 3R) and ensure electrical ratings align with your feeder circuit and control system to maintain regulatory compliance and consistent performance.
Posi-Lok provides a robust mechanical interlock that keeps the handle securely engaged when the switch is in the locked position. This reduces the risk of accidental operation, enhances operator safety, and lowers the likelihood of startup errors during maintenance or changeover, which translates to fewer unplanned outages and improved process stability.
The DH463URKSNLP carries UL Listed certification and a NEMA 3R enclosure rating, indicating suitability for outdoor or exposed indoor installations. It is rated for 100 A and 600 V, which aligns with common industrial feeders and control circuits, ensuring safe isolation and compliance with electrical protection standards in demanding facilities.
While pricing varies by region, the DH463URKSNLP reduces installation time with quick-connect wiring and minimizes downtime through reliable Posi-Lok operation and a rugged Series K design. Savings come from lower labor hours, reduced maintenance interruptions, and extended service life in harsh environments, delivering a favorable return on investment for manufacturing, processing, and distribution operations.
