Device For Connecting An Electric Line To A Circuit Breaker

An electrical switchboard comprising a circuit breaker having a plurality of terminals for input and output electrical connection with an electric line, wherein the electrical switchboard comprises at least one device for connecting said electric line to one of said terminals, said at least one device comprising:

• at least one first electrically conducting body having a first end portion intended to be operatively connected to said terminal, and a second end portion intended to be operatively connected to a conductor element of said electric line;
• and
• at least one thermal conducting body comprising a hermetically sealed cavity containing a cooling fluid, said thermal conducting body being operatively coupled to said first electrically conducting body such that said hermetically sealed cavity has a first surface arranged in proximity to said first end portion and a second surface arranged in proximity to said second end portion.

An electrical switching device having a pair of mutually separable/couplable contacts for opening/closing an associated electric line, and a plurality of input and output connection terminals with said electric line, wherein the electrical switching device comprises at least one connection device comprising:

• at least one first electrically conducting body having a first end portion intended to be operatively connected to one of said terminals, and a second end portion intended to be operatively connected to a conductor element of said electric line;
• and
• at least one thermal conducting body comprising a hermetically sealed cavity containing a cooling fluid, said thermal conducting body being operatively coupled to said first electrically conducting body such that said hermetically sealed cavity has a first surface arranged in proximity to said first end portion and a second surface arranged in proximity to said second end portion.
