fast-actinglow-voltagefor electric motors

Modern motors: Higher efficiency, higher starting currents •Motor manufacturers have improved and partially redesigned their products to enhance their efficiency. •High-efficiency motors have a higher inductivity and smaller copper losses resulting in starting currents higher than those of IE1 and IE2 standard motors. •Consequently, more stringent requirements apply to the switching devices such as contactors, motor protection switches and fuses. When selecting fuses, the increased starting currents shall be taken into account.
