摘要： A switching apparatus for low or medium voltage electric grids, which comprises one or more electric poles. Each electric pole comprises:
- an outer casing made of electrically insulating material and defining an internal volume of said electric pole;
- a fixed contact assembly accommodated in the internal volume of said electric pole and comprising a fixed contact member formed by an electrically conductive tubular element extending along a longitudinal axis of said electric pole;
- at least a movable contact assembly accommodated in the internal volume of said electric pole and hanging laterally relative to said fixed contact member;
- an actuation member accommodated in the internal volume of said electric pole and formed by an electrically insulating hollow tubular element arranged coaxially and externally relative to said fixed contact member, so that said fixed contact member passes through said actuation member along said longitudinal axis. Said actuation member is slidingly movable along said fixed contact member.
In particular, said actuation member is reversibly movable between a first actuation position and a second actuation position by sliding along said fixed contact member.
When moving between said first and second actuation positions, said actuation member transiently couples to each trip mechanism to actuate said trip mechanism.

摘要： A pole actuation booster mechanism for a four-poles low voltage circuit breaker, which comprises: a first operating member adapted to be operatively connected to the operating shaft of the circuit breaker and moving together with said shaft during its rotation from an open position to a closed position, and vice-versa, of said circuit breaker over a range of movement having a first, a second and a third portion of movement, said first operating member having a first operating end; an operating assembly comprising at least an elastic element operatively connected to a lever, the first operating member being disengaged from said operating assembly during said first portion of its movement and engaged with said lever during said second and third portions of its movement. During a closing operation of the circuit breaker said first operating member moves first along said first portion of movement driven by said operating shaft and disengaged form said operating assembly, then moves along said second portion of movement driven by said operating shaft and engaged with said lever and transmitting energy to said operating assembly; and finally moves along said third portion of movement driven by said lever and transmitting energy to said operating shaft.
