Eaton Specification Sheet - DH366UGKLPR
600A, 600V rating enables safe isolation for large motors and feeders, reducing fault exposure and enabling predictable protection. In practice, engineers can dimension feeders with confidence, minimizing overdesign and enabling tighter panel layouts. Three-pole, single-throw operation ensures consistent three-phase disconnection, simplifying control logic and improving motor protection. This also supports straightforward interlock sequencing in drop-in replacements. Unfused fuse configuration reduces component count and simplifies maintenance, lowering spare-part costs and speeding routine servicing. Posi-Lok reverse pin enhances engagement security, reducing the risk of accidental disengagement during servicing and startup checks. The NEMA 1 indoor enclosure provides rugged protection against dust and incidental contact, while the Series K design ensures seamless compatibility with Eaton panels and accessories. Heavy-duty construction and quick-connect wiring contribute to faster commissioning and lower installation labor costs, with proven reliability in demanding industrial environments.
