The invention is related to electric engineering and can be used, in particular, for protection of devices powered by a low-voltage 220V mains against overcurrent. The automatic circuit breaker comprises an automatic circuit breaker with a current release, an inductance connected in series with the load, and a capacitor connected in parallel to the load, further comprising, connected in parallel to the load, a voltage sensor and two thyristors connected in opposition to each other, and a resistor and a current sensor connected in series. The technical result of the invention is protection of users' apparatuses against damage in case of overvoltage or overcurrent that powers the load (apparatus) occurring in the mains. |
