Abstract:
1. A rotating contact supporting shaft for a low-voltage power circuit breaker, having a modular structure that comprises, along the rotation axis, at least one first and one second supporting module, each module being functionally coupled to at least one corresponding moving contact of the circuit breaker and being provided respectively with first and second means for connection to at least one first interconnection module, said first interconnection module being interposed between said first and second supporting modules and being provided with third and fourth connection means that are suitable to be coupled respectively to said first and second connection means, the coupling between said first and third connection means and between said second and fourth connection means allowing the functional connection between said first and second supporting modules and the direct structural connection of said interconnection module to said first and second supporting modules, wherein said first and second supporting modules have a substantially cylindrical body and said first and second connection means comprise three receptacles arranged on at least one of the two end faces of the corresponding cylindrical body, two of said receptacles being arranged substantially symmetrically with respect to each other relative to the rotation axis, a third receptacle being arranged proximate to an edge of the corresponding end face.
