Eaton Specification Sheet - DD325FDKW-00V3
Feature → Business Impact → Application: The enclosure uses NEMA 12 and NEMA 3R protection in painted galvanized steel, delivering dust-tight and weather-resistant performance that reduces panel maintenance and keeps critical circuits protected in harsh environments. This translates to fewer unscheduled shutdowns in manufacturing lines and longer service intervals for electrical rooms. Application: Heavy-duty motor-control centers in manufacturing floors and outdoor installations.Feature → Business Impact → Application: Fuse configuration is fusible without neutral, simplifying wiring schemes and enabling quick fuse replacement without neutral conductors, which lowers maintenance time and minimizes wiring errors. Application: Large three-phase motors and process equipment with high inrush demands.Feature → Business Impact → Application: Amperage rating of 400A and HP ratings up to 250/350 hp at 3PH 480/600 V provide robust protection for high-load motors, reducing nuisance trips while preserving motor life. Application: Pumps, conveyors, and fans in steel, chemical, and mining industries.Feature → Business Impact → Application: Voltage indicator line/load side with a window gives immediate visibility of switch status, improving maintenance planning and safety checks. Application: Panel assemblies and MCCs where quick status verification is critical.Feature → Business Impact → Application: Three-pole, three-wire design with large conductor accommodations [(2) 300 kcmil-#1/0 or (1) 175 kcmil-#1/0] supports flexible feeder configurations, enabling smoother integration with existing plant wiring and reducing retrofitting costs. Application: Power feeds to large motors and three-phase loads in industrial facilities.Feature → Business Impact → Application: UL Listed certification paired with a one-year warranty (or 18 months from shipment) delivers assurance for compliance and supplier support, reducing risk in procurement and installation. Application: Project rollouts and retrofit programs across manufacturing, packaging, and processing sectors.
