Abstract: A medium voltage circuit switch or breaker includes: at least one movable contact; a fixed contact; and a mechanical or magnetical drive system, which moves the at least one movable contact to a closed or opened position by a movement of a rod and/or a lever. The mechanical or magnetical drive system is linked to a switching generating signal. The mechanical or magnetical drive system includes at least one pyrotechnical actuator or gas generator. The pyrotechnical actuator or the gas generator is linkable to the switching generating signal of the mechanical or magnetical drive system.

Abstract: A pivot supporting structure for a circuit breaker and a circuit breaker. The pivot supporting structure comprises: a supporting body having a supporting hole for receiving and pivotally supporting a pivot pin connected to an actuating mechanism of the circuit breaker, wherein at least one strain gauge are mounted to the supporting body for sensing the force acting on the pivot supporting structure by the actuating mechanism. This pivot supporting structure can accurately sense the characteristic force applied, such that the contact force and mechanical characteristics of the circuit breaker can be on-line monitored.
