Note: The listed data is based on approximate full-load current ratings of standard, open, 1.15 service factor, continuous rated GE motors. Full-load current ratings of similar motors of other manufacturers may vary considerably. Therefore, whenever possible use actual full-load current rating given on motor nameplate. Contact motor manufacturer for full-load currents of single-phase and DC motors.
1 For expected values on 208-Volt , 50-Hertz, three-phase motors, contact nearest GE Representative.
2 Open, Type K, General-Purpose, NEMA SF, Solid-Base, Rolled-Steel-Shell, GE Induction Motors.
