Abstract: Interlock structure for a circuit breaker is constructed and arranged such that 1) when a control plug is disconnected from a socket, a portion of a linkage structure engages a racking linkage, causing a portion of the racking linkage to engage a racking screw, preventing the racking screw from rotating and thus preventing racking of the circuit breaker, and 2) when the control plug is connected with the socket, the linkage structure is actuated thereby moving the portion of the linkage structure to disengage from the racking linkage such that the portion of the racking linkage disengages from the racking screw, permitting the racking screw to rotate thereby permitting the circuit breaker to be racked to a connected position, where the primary contacts are connected to the main bus.

Abstract: A door for an arc-resistant compartment includes an opening there-through. Flap structure includes a flap member coupled to the door and movable between an opened position permitting air to pass through the opening, and a closed position covering the opening. Spring structure is engaged with the flap member to bias the flap member to the closed position. Handle structure is coupled to the flap member and extends through the door for moving the flap member to the opened position against the bias of the spring structure. Retaining structure provides a retaining force on the flap member to retain the flap member in the open position, against the bias of the spring structure. During an arcing event in the compartment, pressure within the compartment together with the bias of the spring structure overcomes the retaining force to automatically move the flap member to the closed position.

Abstract: A connecting device suitable for connecting a movable conducting terminal of a switching device to a stationary conducting terminal of a switchgear apparatus, includes: a pin-group suitable for being inserted into an opening obtained in a connection-region which is defined by mutually overlapping portions of the movable and stationary conducting terminals. The pin-group is movable from a releasing position to a locking-clamping-position. There is provided a locking-positioning-arrangement configured for keeping the pressing-clamping-end blocked in the locking-clamping-position and for imparting to the pressing-clamping-end, upon a movement of the pin-group from the releasing position to the locking-clamping-position, a tightening displacement so as to generate a tightening force which presses the mutually overlapping portions against to one other. The connecting device is provided with a tightening-control-arrangement configured for controlling the tightening force so as to set a desired value of tightening-contact-pressure between the mutually overlapping portions.
