Abstract: A contactor for medium voltage electric systems including: one or more electric poles; for each electric pole, a fixed contact and a corresponding movable contact reversibly movable between a first position, at which the movable contact is decoupled from the fixed contact, and a second position, at which the movable contact is coupled with the fixed contact; an electromagnetic actuator including a magnetic yoke having a fixed yoke member and a movable yoke member, the movable yoke member reversibly movable between a third position corresponding to the first position of the movable contacts, at which the movable yoke member is decoupled from the fixed yoke member, and a fourth position, corresponding to the second position of the movable contacts, at which the movable yoke member is coupled with the fixed yoke member, the electromagnetic actuator including an excitation circuit assembly including an excitation coil wound around the magnetic yoke and electrically connected with an auxiliary electric power supply to be fed with an excitation current to generate an excitation magnetic flux to move the movable yoke member from the third position to the fourth position or to maintain the movable yoke member in the fourth position; an opening springs operatively coupled with the movable yoke member to move the movable yoke member from the fourth position to the third position; a kinematic chain to operatively connect said movable yoke member with said movable contacts. The electromagnetic actuator including camping circuit assembly comprising a damping coil arranged to form a conductive loop adapted to be at least partially enchained with the excitation magnetic flux generated by the excitation current flowing along the excitation coil, when the auxiliary electric power supply provides the excitation current to the excitation coil, so that a secondary current circulates along the damping coil when the excitation magnetic flux is subject to a transient.

Abstract: A mechanical latching accessory kit (1) for a Medium Voltage contactor (100) comprising one or more movable contacts (101) connected through a mechanical link (110) to a contact actuator (102) moving said one or more movable contacts (101) between a contact open position and a contact closed position. The mechanical latching accessory kit (1) comprises: a supporting interface (2) adapted to be fixed to and removed from said Medium Voltage contactor (100); a latching element (3) movable between a first operating position and a second resting position; a latching actuating system (4) moving said latching element (3) between said first, operating, position and said second, resting, position; said latching element (3) being adapted, when it is in said first operating position, to cooperate with the mechanical link (110) of said Medium Voltage contactor (100) to latch said one or more movable contacts (101), and, when it is in said second resting position, to release said one or more movable contacts (101).
