earth-leakagemanualautomatic

The residual current device works with no extra power supply to the operating mechanism. It compares the magnitude of the currents through the neutral and phase conductors. switching off heavy-loaded electrical circuits at insulation damage of the conductors to the consumers switching off heavy-loaded electrical circuits at presence of a person under voltage used to protect not only particular consumers/ circuits, but also the whole panel remarkable with high reliability of current characteristics control: manual switching on and automatic switching off at exit failure
