Device for connecting bus bars

An electric switchboard comprising a plurality of electrical devices, such as circuit breakers and the like, which are electrically connected to corresponding bus bars, comprising a connecting device further comprising a single body made of conducting material which has three elements which lie along three substantially mutually perpendicular planes, of which:

• a first flat base element has a first outer side and a second outer side which are arranged in an L-shaped configuration with respect to each other, a third inner side and a fourth inner side being arranged in an L-shaped configuration with respect to each other and being substantially parallel to the corresponding outer sides;
• a second flat element is arranged along said first outer side of the first element;
• a third flat element is arranged along said second outer side or along said fourth inner side of the first element, the second flat element and the third flat element being arranged along the corresponding sides so that their minimum relative distances, considered as the distance between one end of the second element and the plane on which the third element lies, and the distance between one end of the third element and the plane on which the second element lies, respectively, allow the free passage of the bars, said first, second and third flat elements being further provided with a plurality of slots suitable to receive means for connection to the bars.
