2010年11月25日 · NEMA electrical motor starters refer to a standardized rating system for the electrical performance of the most common style of American-built motor starters. NEMA starters are rated by size: 00, 0, 1, 2, 3, 4, 5, 6 and 7. Maximum electrical motor horsepower for different NEMA starters for three phase motors can be found in the table below:
European or U. S. style starters can be replaced without changing wiring layout. The NEMA Sizes 6-8 features a special DC feeder group for coil feeding. This system allows AC or DC applied voltage, low noise and low inrush and holding consumption. The NEMA Size 9 coil is 110V dc/120V ac (Rectified). AC or DC magnet coils.
