Features, benefits and range Short time duty (S2) and intermittent periodic duty (S3); duty cycles S4 ... S10 In case of a duty-requirement type S2 ... S10 the motor power can be increased as per the following table; starting torque keeps unchanged. Short time duty (S2). – Running at constant load for a given period of time less than that necessary to reach normal running temperature, followed by a rest period long enough for motor’s return to ambient temperature. Intermittent periodic duty (S3). – Succession of identical work cycles consisting of a period of running at constant load and a...
