Abstract

PURPOSE: To prevent the degree of defectiveness of an appliance or circuit from increasing, by hindering the restoring operation of a protective detector by a resetting unit and opening the defective appliance or circuit depending on the number of times of repetition of the restoring operation.
CONSTITUTION: The protective detector consists of a high-speed circuit breaker HB, an overcurrent relay OCR1 for a first group and an overcurrent relay OCR2 for a second group. When the high-speed circuit breaker operates, the restoring operation by a reset switch RS can be performed once. When the relays OCR1, OCR2 operate, the restoring operation can be performed up to two times. Main motor breakers COS11WCOS22 and the relays are operated when the restoring operation is performed three or more times. A memory CD is provided so that it operates in response to the AND of the operation of the protective detector with a resetting operation. When the number of repetition of the restoring operation reaches a predetermined value, the motor breakers and the relays are caused to operate in connection with the resetting operation.
