FAQs
The DH365URKSNLPR is a three-pole, 400 A, 600 V device designed to fit standard motor control center footprints with the Series K interface. It is unfused, requiring coordination with upstream protection devices. Dimensions (32.87 in deep, 74.34 in tall, 16.1 in wide) should be matched to existing enclosures and mounting provisions to ensure seamless retrofit or new-install compatibility.
This safety switch carries UL Listed certification and uses a NEMA 3R enclosure, enabling outdoor or damp environments. The Posi-Lok reverse pin adds secure actuation, reducing accidental opening. While not all markets require SIL, CE, or IP ratings, UL Listing and NEMA 3R conformance provide strong regulatory and environmental performance for industrial applications.
Outdoor installations demand proper space for clearance and rigging due to the unit’s 370 lb weight and tall footprint (74.34 in height). Ensure weather protection, appropriate mounting, and external fuse coordination if used. Plan for service access, lifting equipment, and alignment with downstream devices to maintain reliable operation under harsh conditions.
The product is covered by Eaton’s 25-000 warranty policy, offering one year from installation or eighteen months from shipment, whichever comes first. This warranty, combined with UL Listing and documented specifications, supports procurement risk management and provides assurance during the system’s initial operation lifecycle.
Investing in the DH365URKSNLPR can reduce downtime from reliable isolation and safer maintenance, boosting line uptime in high-demand facilities. The rugged NEMA 3R enclosure and Series K design offer long service life and easier integration with existing protection schemes, delivering predictable lifecycle costs and improved safety over conventional fuses and smaller switches.
