Eaton's Motor starters and „Special Purpose Ratings“ for the North American market Technical Paper provides information about special purpose ratings for motor starters, including elevator control, refrigeration control, resistance air heating and incandescent lamps (tungsten) applications.
The document provides an overview of North American terminology and standards for motor starter applications, comparing them with IEC classifications. It explains general purpose, special purpose, and definite purpose ratings, and details how load types map to utilization categories such as AC‑1, AC‑2, and AC‑3.
It also presents selection tables for Eaton Moeller contactors (DIL M, DIL K) and motor starter combinations, including UL‑ and CSA‑certified devices, back‑up protective switch types (E and F), and NEMA size ratings. The paper concludes with validity notes and references to related technical documents.
