Eaton Specification Sheet - EDS21100 P31 SA
Two-pole configuration with a built-in dead-end style simplifies motor control wiring by limiting the number of conductors and eliminating extra junctions. This reduces panel complexity and installation time, delivering faster commissioning for pumps, conveyors, and fans in hazardous environments. The with-switch enclosure design provides convenient manual control in a compact, single-gang footprint, enabling straightforward installation in space-constrained panels and minimizing wiring errors. Copper-free aluminum enclosure delivers corrosion resistance in harsh environments, supporting reliable operation in chemical, mining, and petrochemical facilities while reducing maintenance costs. The 3/4 inch hub and 1 hp rating ensure compatibility with common small motors used in machine tools and material handling lines, easing stock management and spares planning. Integrated 6.83A Allen Bradley heater lowers nuisance tripping and improves cold-start performance, translating to fewer disruptions during start-up and seasonal operation. NEC/CEC compliance and UL certifications for hazardous locations, along with NEMA ratings 9 3 7, provide regulatory assurance and safer installation in classified areas, helping you meet stringent safety standards while optimizing total cost of ownership.
