Self-recovering current-limiting device having liquid metal

A self-recovering current-limiting device including a liquid metal, the 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, the plurality of insulating bodies defining a trough-like bottom part configured for supporting the first and second electrodes;
• a plurality of insulating intermediate walls, the plurality of insulating intermediate walls and the plurality of pressure-resistant insulating bodies defining a plurality of first compression spaces, the plurality of first compression spaces being disposed one behind the other between the first and second electrodes and being at least partially filled with the liquid metal, the plurality of insulating intermediate walls defining a plurality of connecting channels as upwardly open slotted holes, the plurality of insulating intermediate walls being integrally connected to the bottom part;
• and
• a cover configured for tightly closing the bottom part using at least one of a nonpositive-locking and positive-locking connecting device, the cover and the bottom part forming a housing.
