Eaton Specification Sheet - EMN24 W31 0
The EMN24 W31 0 is a three-pole, three-phase manual line starter housed in a copper-free aluminum enclosure (NEMA size 1). It ships with the starter included and supports a broad 115–600 VAC supply while accommodating motors up to 10 HP. The lightweight enclosure reduces panel depth and simplifies field mounting, making it well-suited for limited-space control cabinets in industrial plants. The unit is designed for hazardous locations and meets NEC/CEC standards with certifications for Class I Division 1/2, Class II Division 1/2, and Class III, plus NEMA ratings 3, 7, 9, 12. This combination ensures regulatory alignment and reliable protection in tough environments. The HP range and voltage window enable a single starter to cover several motor applications, reducing spare parts and procurement complexity in maintenance programs. Copper-free aluminum delivers corrosion resistance with a lighter form factor, aiding installation and longevity, while the Omit heater option reduces ongoing maintenance and parts exposure. The inclusion of the starter simplifies commissioning and minimizes wiring errors, and comprehensive Eaton documentation supports best-practice installation and service in hazardous-area facilities.
