Abstract: A switching apparatus for electric power distribution grids including a first switching unit having one or more first electric poles, each first electric pole being electrically connectable with a corresponding first line conductor of an electric line and including one or more solid-state switches adapted to operate in a conduction state or in an interdiction state to allow or interrupt a current flow, and a second switching unit having one or more second electric poles, each second electric pole being electrically connectable with a corresponding second line conductor of said electric line and electrically connected in series with a corresponding first electric pole of said first switching unit. The switching apparatus further includes a controller implementing a robust control logic to the operation of said first and second switching units.

Abstract: A circuit breaker includes a first fixed contact and a first movable contact which can be switched between a closed status and a tripped status, a signaling device for signaling when the circuit breaker is in a tripped status, a trip actuator movable from an initial position to an end-stroke position when the first movable contact is switched from the closed status to the tripped status, a tripping bar which is connected to the first movable contact so as when the trip actuator moves from the initial position, the tripping bar moves and triggers switching of the first movable contact from the closed status into the tripped status, and a trip member having a single-piece shaped body, which includes a first portion actuated by the trip actuator, a second portion spaced apart from the first portion, and a third portion spaced apart from the first and second portions.

Abstract: A circuit breaker including: a first fixed contact and a first movable contact which can be switched between a closed status where they are coupled to each other and a tripped status where they are separated from each other; a signaling device for signaling when the circuit breaker is in a tripped status; a trip actuator movable from an initial position to an end-stroke position when the first movable contact has to be switched from the closed status into the tripped status; a tripping bar which is connected to the first movable contact so as when the trip actuator moves from the initial position, the tripping bar moves and triggers switching of the first movable contact from the closed status into the tripped status; and a trip member having a single-piece shaped body which includes: a first portion interacting with and actuated by the trip actuator to move from a rest position towards an actuated position when the trip actuator moves from the initial position; a second portion which is spaced apart from the

Abstract: The invention relates to an accessory device assembly for a low or medium voltage switching device. The accessory device assembly comprises at least a first accessory device comprising a first external housing, first electrical connection means for electrical connection with said switching device, second electrical connection means for electrical connection with outside equipment, third electrical connection means for electrical connection with a second accessory device, first mechanical connection means for mechanical connection with said second accessory device and second mechanical connection means for mechanical connection with said switching device.

Abstract: The present invention relates to a switching device for low voltage systems comprising one or more accessory devices. The switching device according to the invention comprises a case containing at least one pair of contacts that can be reciprocally coupled/decoupled. The device furthermore comprises a containment structure to contain at least one accessory device of the switching device. Said structure is provided with means for interfacing with the accessory device which comprises a body that can be inserted in the containment structure. The accessory device also comprises coupling means to couple it to the containment structure and operating means which interact with the switching device via the interface means of the containment structure. The accessory device is also provided with disengagement means operatively connected to the coupling means. Said disengagement means, once activated, free the coupling means to permit extraction of the accessory device from the containment structure.
