FAQs
What mounting and wiring practices optimize performance for the DH464URKSNLP? Its four-pole, unfused design requires appropriate sized conductors and clean, accessible wiring paths. Use the Series K footprint for compatibility with existing panels, account for the 140 lb weight during handling, and ensure proper secure mounting in a protected, code-compliant enclosure to maintain UL Listing and NEMA 3R integrity.
Posi-Lok provides a tactile, positive-lock mechanism that prevents inadvertent opening of the disconnect. This reduces the risk of arc flash exposure during maintenance and minimizes unplanned downtime. For installations with frequent access, Posi-Lok offers a dependable engagement that engineers can trust under variable thermal and vibration conditions.
Yes. The DH464URKSNLP is designed as a Series K product with an unfused, four-pole configuration, and the NEMA 3R enclosure supports outdoor and semi-exposed installations. UL Listed certification further confirms suitability for harsh environments, enabling reliable operation across manufacturing floors, outdoor substations, and control rooms that require rugged protection.
This safety switch carries UL Listed certification and uses a NEMA 3R enclosure, aligning with common industrial safety and weather-protection standards. These certifications facilitate procurement within regulated environments, simplify vendor audits, and help meet plant-wide safety policies, reducing the need for additional product testing or extra protective enclosures.
The combination of quick-connect wiring, Posi-Lok reliability, and a robust 200A/600V rating translates to shorter installation times, fewer field faults, and reduced maintenance visits. Although the unit is heavy, its durable construction and UL/NEMA-compliant design lower long-term maintenance costs and downtime, contributing to a favorable total cost of ownership in high-demand automation environments.
