Abstract: Described herein is a switching apparatus for low or medium voltage electric grids, which includes one or more electric poles. Each electric pole includes: an outer casing defining an internal volume of the electric pole; a fixed contact assembly accommodated in the internal volume of the electric pole and including a fixed contact member extending along a longitudinal axis of the electric pole; at least one movable contact assembly accommodated in the internal volume of the electric pole; an actuation member accommodated in the internal volume of the electric pole and arranged coaxially and externally relative to the fixed contact member, so that the fixed contact member passes through the actuation member along the longitudinal axis. The actuation member is slidingly movable along the fixed contact member. When moving between the first and second actuation positions, the actuation member transiently couples to each trip mechanism to actuate the trip mechanism.

Abstract: In one aspect, a hybrid circuit protection device for current-limiting a fault current between a source and a load during a fault is provided. The hybrid circuit protection device includes an input configured to couple to the source, an output configured to couple to the load, a return configured to couple the source to the load, a main switch configured to selectively couple the input to the output, a switching network coupled in parallel with the main switch, and a controller. The controller is configured to determine that the main switch has opened in response to the fault current, where the fault current has an initial value, and activate the switching network to current-limit the fault current to less than the initial value during the fault.

Abstract: A low-voltage circuit breaker includes at least one fixed contact, for each pole, which is electrically connected to a terminal for connection to an electric circuit, and a corresponding moving contact which is associable/separable with respect to the fixed contact by a rotation of the moving contact. The low-voltage circuit breaker further includes an arc chamber positioned in correspondence of the fixed contact, and a rotating contact supporting shaft common to all poles, which is functionally connected to an actuation mechanism of the circuit breaker, where the actuation mechanism includes a kinematic system operatively connected to an actuation lever for opening/closing operations and provided with opening springs and a tripping shaft for releasing the kinematic system and allowing its movement from a closed to an open position. The low-voltage circuit breaker further includes, for each pole, a quick acting trip device.
