Abstract
PURPOSE: To provide a three-dimensional trip characteristic with compactness less affected by a thermal effect, by such means that a long time limit be obtained from the output of current transformer through a time delay mechanism of electromagnetic coil type, and short-time limit trip-and momentary trip-characteristic further obtained by the above output and a semiconductor circuit.
