Abstract
A high voltage circuit breaker with insertion of resistance on closing, wherein the resistance is inserted by a fixed insertion electrode co-operating with the end of the moving main contact, the blast nozzle and the arcing contact of the moving assembly being secured to each other, and the subassembly being movable relative to the moving assembly so that on triggering, because of the inertia of said subassembly, the arcing contacts separate after the insertion electrode and the end of the moving main contact have moved sufficiently far apart.
