Eaton Specification Sheet - DH465URKSNLPR
Feature: 400A four-pole disconnect rated for 600V provides a single, decisive isolation point for heavy motor loads. Business Impact: this high-current capability reduces the need for multiple devices, streamlines protective-coordination, and lowers arc-flash exposure during maintenance. Application: ideal for large motor feeders on conveyors, pumps, and processing lines in harsh industrial environments such as metals, mining, and water treatment facilities. Feature: Posi-Lok reverse pin ensures positive alignment and secure operation during coupling and maintenance. Business Impact: minimizes mis-wiring and interlock failures while accelerating field service with clear tactile feedback. Application: especially valuable in outdoor enclosures and retrofit projects where you rely on repeatable, safe actuator positioning. Feature: NEMA 3R enclosure delivers weatherproof, corrosion-resistant protection. Business Impact: lowers downstream maintenance costs and extends service life in outdoor or damp spaces, reducing unscheduled downtime. Application: suitable for exterior switchgear installations, loading docks, and process-area protection where exposure to rain and dust is common. Feature: Series K design ensures compatibility with Eaton mounting interfaces and accessories. Business Impact: streamlines procurement, stocking, and spare-part availability, cutting project lead times and enabling faster commissioning. Application: integrates seamlessly with existing Eaton architectures and supports clean, modular installations in new builds and upgrades. Feature: UL Listed certification and a formal warranty (one year from installation or eighteen months from shipment). Business Impact: supports regulatory compliance, risk management, and predictable budgeting for service needs. Application: trusted in regulated facilities and critical uptime environments where documented safety certification matters. Feature: Unfused fuse configuration simplifies downstream protection architecture. Business Impact: reduces component count and potential failure points while enabling tailored protection schemes. Application: appropriate where upstream protection is provided by specific upstream devices or rapid installation is required. Feature: Integrated installation guidance and ergonomic access simplify alignment, wiring, and testing during commissioning. Business Impact: reduces on-site engineering time, accelerates start-up, and lowers project risk with repeatable Eaton standards. Application: supports efficient field rollout in new builds and upgrades.
