Abstract

PURPOSE: To prevent hunting common to the convention device through easy setting and alteration of tripping property to match the load characteristic of the power equipment by external setting operation.
CONSTITUTION: This apparatus is equipped with a detector 13 which provides pulse signals in number proportional to the service power, a down counter circuit 19 for pulse conversion of the pulse signals, a setting device 25 for setting control target, a digital comparator circuit which provides an output whenever the output of the circuit 19 exceeds the set value of the setting device 25 and a timer 22 which is actuated by the output of the comparator circuit to open load control contact after a given time for cutting the power supply to the load. With such an arrangement, a digital processing is performed through combination of the down counter circuit, the digital comparator and the like, thereby assuring power controlling property according to the load characteristics of the power equipment and ultimately stabilizing the power administrative control.
