 NEMA (National Electrical Manufacturers Association)
 
NEMA is the leading trade association in the U.S. representing the interests of electrical industry manufacturers of products used in the generation, transmission and distribution, control, and end-use of electricity.

NEMA provides a forum for the standardization of electrical equipment, enabling consumers to select from a range of safe, effective, and compatible electrical products. NEMA publishes over 500 standards.

 
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
.

To select a NEMA starter only horsepower and voltage are needed. NEMA starters have interchangeable heater elements and makes NEMA starters attractive in projects where the motor specification is not known until the start-up date.
