Self-recovering current limiting device with liquid metal

A self-recovering current-limiting device comprising:

• a first and a second electrode for connection to an electric circuit to be protected, each of the first and second electrodes being made of a respective solid metal;
• a plurality of pressure-resistant insulating bodies;
• and
• a plurality of insulating intermediate walls supported by the plurality of insulating bodies;
• wherein the plurality of insulating intermediate walls define a plurality of connecting channels therein and wherein the plurality of insulating intermediate walls and the plurality of pressure-resistant insulating bodies at least partially define a plurality of compression spaces, the plurality of compression spaces being disposed one behind the other between the first and second electrodes and being at least partially filled with a liquid metal, a level of the liquid metal above the connecting channels being changeable using an adjusting device.
