Abstract: The present application concerns a circuit breaker including a movable contact, a driving rod slidably mounted in the circuit breaker, a linkage mechanism for driving the movable contact, a pivoted driving fork rotatably mounted in the circuit breaker which cooperates with the driving rod through the cooperation of a primary pin provided on the driving rod and a primary slot provided on the driving fork, a driven lever connecting the driving fork to the movable contact, and wherein the driving rod supports a secondary pin which cooperates with a secondary slot of the driving fork when the driving rod in a position between a predetermined position and an extreme opened position of the circuit breaker.

Abstract: Provided herein is an electric arc-blast nozzle for a circuit breaker comprising a median part internally defining an axial electric arc cut-off passage and formed with a first dielectric material, first and second end parts formed with the first dielectric material and extending on either side of the median part and being intended to receive first and second arc contacts being axially moveable in relation to each other. The nozzle further comprises a sheath that is disposed on the external surface of the first end part and on a portion of the external surface of the neck-forming median part, said portion having the same radial external section than the first end part, is formed with a second dielectric material different from the first dielectric material and is obtained from a second composition comprising a thermoplastic polymer chosen from either a polysulfone or a polyetherimide, but not comprising fibrous reinforcements.

Abstract: A contact arrangement for a Pre-Insertion Resistor (PIR) wherein a control rod is arranged to move a movable contact, against the force of a biasing member, into temporary connection with a PIR. The control rod comprises a tulip with a plurality of resilient fingers and having a first diameter where it is able to mechanically couple to a latching ring on the movable contact, and a second diameter where the tulip is deformed with the fingers deflected inwards, once the resistance to movement exceeds a predetermined value, wherein the latching ring is able to pass over the tulip to decouple the movable contact from the control rod. The contact arrangement is particularly suited for a PIR arranged for connection in parallel to the interrupter of a gas-insulated switchgear (GIS) circuit breaker.
