Automatic shutdown

— automatic devices that protect electrical networks from short circuits and overloads. In both cases, the current flowing through the circuit increases significantly, which can lead to equipment breakdowns and fires. The circuit breakers respond precisely to a critical increase in current strength, opening the circuit in such cases. The presence of such protection is almost mandatory for any electrical network.
