Eaton Specification Sheet - DH466URKSNLPR
600A amperage rating directly protects feeders and motors, reducing nuisance trips and equipment damage while delivering measurable uptime gains for critical processes. Business impact: improved reliability, lower maintenance costs, and better overall plant availability. Application: ideal for large, high-load installations in manufacturing floors, data centers, and distribution hubs. 4-pole configuration provides full-load isolation with a compact footprint, enabling streamlined panel layouts and safer servicing in confined spaces. Application: retrofit opportunities in legacy switchgear where upgrade to heavy-duty, unfused protection is required to meet modern codes. NEMA 3R enclosure offers outdoor readiness and environmental resilience, reducing corrosion-related downtime and enabling year-round operation in exposed locations. Business impact: fewer weather-related failures and extended service life in harsh environments. Posi-Lok reverse pin ensures positive engagement of handle and mechanism, addressing concerns about misalignment in heavy or vibration-prone installations. Application: critical in facilities with heavy machinery, conveyors, and motions systems where secure positioning matters for safety and compliance. UL Listed certification and Series K compatibility streamline procurement, installation, and maintenance workflows, delivering faster commissioning and reduced risk during audits. Business impact: stronger compliance posture, simplified training, and clearer maintenance protocols. Warranty information reinforces total-cost-of-ownership benefits by providing a clearly defined coverage window, supporting long-term planning and budget certainty.
