5. The State of the Market
NEMA largely has its base in North America, with some presence in some parts of the
world. The presence is mostly in areas with large U.S. influences, like U.S. companies
based in the Middle East.
Over several years, many companies have shifted from NEMA-style contactors and
starters to IEC ones. The conversion has leveled off by market segments. Those in
commercial and light industries have nearly completed the transition to IEC.
Those in process industries have proactively remained with NEMA-style devices. In
terms of the number of products sold, IEC-style ones outsell NEMA-style ones. In dollar
value, NEMA-style devices outsell IEC products.
