A method of operating an apparatus for protecting a protected circuit from arcing comprising: a current signal at a high frequency band, a current signal at an intermediate frequency band, a voltage signal at a low frequency band, and a voltage signal at an intermediate frequency band are measured in each voltage half-cycle. Determining the presence of a separated arc in each voltage half-cycle based on the measured signal; information about the separated arc is collected over a set period of time and stored in the form of arc parameters. When the arc parameter reaches a set value, the arc is recorded and a signal is generated to disconnect the protected circuit from the network. The device (1) for protecting a circuit from arcing comprises a voltage reading unit (2), a current sensor (3), a high-frequency current signal detection unit (4), an intermediate-frequency current signal detection unit (5), a microcontroller (6), a power supply unit (7) and a disconnection means (8). The technical result of the invention consists in increasing the accuracy of determining the arc events, reducing the number of false activations of the arc protection devices, and increasing the working range, the number of electrical appliances connected, the length of the protected circuit and the number of branches it contains.)
