An electrical coupling bar is described. The coupling bar includes an electrically insulating support with two parallel grooves and metallic strips engaged in the grooves. The metallic strips project out of the grooves with opposite interior faces delimiting a free engagement space. Further, the other surfaces of metallic strips of the coupling bar are covered for protection.

Electrical connection bar and adapted connection device

An electrical coupling bar is described. The coupling bar includes an electrically insulating support with two parallel grooves and metallic strips engaged in the grooves. The metallic strips project out of the grooves with opposite interior faces delimiting a free engagement space. The coupling bar further includes metallic strip protection means covering the other faces of the metallic strips.

This invention concerns a system for the protection of electric circuits (60, 61, 62) which permits an analysis in real time of the evolution of electric currents circulating in such electric circuits, such analysis having as its purpose not only protection but also prevention. Such protection system comprises at least one circuit breaker (64, 66) including a first coil (70, 71) associated with a magnetic circuit and bearing the main current, as well as a second coil (74, 75) likewise associated with the magnetic circuit. Such second coil carries an induced current representative of the main electric current. Such induced current is processed by an electronic circuit (80) which supplies a processed signal representative of at least one characteristic of the main current, said characteristic being used for prevention in the electric circuits.
