Abstract (en)
High- or medium-voltage circuit breaker with end arc contacts, comprising a sealed insulating envelope (1) filled with a gas with good dielectric properties, inside which are arranged a fixed arc contact (3-3A), a moving arc contact (7-7A) driven by an operating rod (26) actuated by a mechanism outside the envelope, a blast chamber (17) comprising a piston (9) integral with the moving arc contact and able to slide in a fixed cylinder (14), and a blast nozzle (12), characterised in that it comprises means (24) such that the operating rod moves over a given length without driving the said arc contact. <IMAGE>
