Selecting The Correct Motor Starter
Motor Full Load Current Table

AC Motors - Full Load Current Tables (1450 RPM Approx.)
(Provided as a guide to the selection of suitable Eaton MEM control gear).

The tables are based on motors of approx. 1450 rpm of average efficiency and power factor. Motor of higher speed than 1450 rpm usually take a lower current than that shown in the table; while motors of lower speed usually take higher current.

Wide variations from these figures can arise, especially on single phase motors and engineers should, whenever possible, determine the actual f.l.c. from the motor rating plate in each case.
