Abstract
An auxiliary/control switches kit box for a Medium Voltage switching device including one or more movable contacts operated between a contact open position and a contact closed position by a kinematic chain connected to a contact actuator. The auxiliary/control switches kit box includes: a shaped enclosure adapted to be inserted into and removed from a dedicated volume inside the Medium Voltage switching device; the shaped enclosure housing one or more auxiliary/control switches electrically connected to corresponding one or more terminal boards; the one or more terminal boards facing toward the outside of the shaped enclosure from a first face of the shaped enclosure; the one or more auxiliary/control switches each including a pair of auxiliary/control switch contacts that can be linearly operated by an auxiliary/control switch actuator between a normally open (NO) position and a normally closed (NC) position; a mechanical coupling system mechanically connected to the auxiliary/control switch actuator to linearly displace it between the NO position and the NC position; the mechanically coupling system having one or more operating levers protruding outside the shaped enclosure from…
