A rapid cutoff device includes a thyristor AC switch for supplying an AC current from a first AC circuit to a second AC circuit. A serially-connected circuit of a first switch and a first capacitor parallel-connects with the first AC circuit. A serially-connected circuit of a second switch and a second capacitor parallel-connects with the second AC circuit. When cutting off the thyristor AC switch, the first switch is operated to conduct the first capacitor in a first direction for the AC current charging to the first capacitor, alternatively, the second switch is operated to conduct the second capacitor in a second direction for the AC current charging to the second capacitor, thereby lowering a current in the thyristor AC switch approaching a zero value and thus rapidly cutting off it.
