るブレーカトリツプ監視装置。[Claims for Utility Model Registration] A counter that counts input pulses to each breaker branched out along a bus line and that sets different preset values as the address of the breaker to which it belongs; When the count value reaches a preset value, if the trip contact of the breaker is activated, a trip detection section consisting of a trip signal generation circuit that outputs a trip pulse signal with a time width shorter than the pulse generation interval is attached. a pulse generating circuit that sends out pulses that cause each of the counters to count, and a reset pulse generating circuit that sends out a reset pulse that resets each of the counters every time a predetermined number of the pulses are generated; The circuit comprises: a determination circuit that determines which breaker of the address has been tripped from the number of pulses generated after the reset pulse is generated at the time when the trip pulse signal is input; and a notification means that notifies the result of the determination. A breaker trip monitoring device consisting of:
