PURPOSE: A condenser trip device is provided to safely control and protect the high pressure vacuum electronic contact upon occurrence of power outage. CONSTITUTION: A condenser trip device comprises input terminals(11,12) for applying an AC power; a varistor(TNR) for removing the surge of the AC power applied to the input terminals; condensers(C2,C3,C4) and bridge type diodes(D2,D3,D4,D5) connected in parallel to the input terminals and which performs a full-wave rectification to the alternating current; a relay(K1) connected to the condensers and the bridge type diodes, and which controls outputs(13,14) of contacts in accordance with the application of the AC power; a diode(D1) for performing a half-wave rectification to the AC power of the input terminals; a condenser(C1) for charging the DC power which is half-wave rectified by the diode and a discharge switch(S/W1) for discharging the charged power; an LED(LED1) for displaying the charged state of the condenser; and output terminals(15,16) connected in serial to the input terminals, and which outputs the power by the discharge of the condenser.
