Abstract: Disclosed is a discontinuous jump current breaker, in an AC power system having an insulating material that exhibits nonlinear electrical characteristics between two electrodes, which blocks an AC power by observing a discontinuous jump current in which an insulator-metal transition occurs. The discontinuous jump current breaker includes a setting unit that sets the magnitude of a discontinuous jump current, a sensor unit including a metallic wire (Republic of Korea Patent Registration No. 10-1981640) parallel to an AC power wire, located at a separation distance d≥0, and that measures electromagnetic waves of an AC power, an amplifier unit that amplifies an analog signal of the metal wire, an analog-to-digital converter that converts the amplified analog signal to digital, a microcontroller unit including a memory unit for storing a program that drives the system, and a power blocking unit that blocks the discontinuous jump current.
