Tcca Ia Motor Full Load Current Chart Selection Tables - Three-Phase Motors Motor hp Approx. F.L.C. at line voltage Rating 220V ac 240V ac 380V ac 415V ac 550V ac AC Motors - full load current tables (1450rpm approx.) provided as a guide to the selection of suitable MEM control gear. The tables are based on motors of approximately 1450rpm of average efficiency and power factor. Motors of 0.1 kW 1/8 0.7 0.6 0.4 0.4 0.3 higher speed usually take a lower current than that shown in the table; while motors of lower speed usually take 0.12 kW 1/6 1 0.9 0.5 0.5 0.3 higher current. Wide variations from these figures can arise, especially on single phase motors, and engineers 0.18 kW 1/4 1.3 1.2 0.8 0.7 0.4 should, whenever possible, determine the actual f.l.c. from the motor rating plate in each case. 0.25 kW 1/3 1.6 1.5 0.9 0.9 0.6 0.37 kW 1/2 2.5 2.3 1.4 1.3 0.8 0.56 kW 3/4 3.1 2.8 1.8 1.6 1.1 0.75 kW 1 3.5 3.2 2 1.8 1.4 1.1 kW 1.5 5 4.5 2.8 2.6 1.9 1.5 kW 2 6.4 5.8 3.7 3.4 2.6 2.2 kW 3 9.5 8.7 5.5 5 3.5 3.0 kW 4 12 11 7 6.5 4.7 3.7 kW 5 15 13 8 8 6 Motor Approx.
