Abstract: The invention relates to a circuit breaker (10) for an electricity transport installation, the circuit breaker comprising a tank (12), a vacuum bottle (20) that has a stationary contact (24), a movable contact (26), and sealing means (40), a casing (30) that is arranged inside the tank (12), that electrically connects the movable contact (26) to an electrical conductor (18), and that co-operates with an outside wall of the vacuum bottle (20) to define a volume (42) that is taken to a pressure close to atmospheric pressure, and feeder means for feeding the inside volume (42) of the casing (30), which feeder means pass through the inside volume (14) of the tank (12), the circuit breaker being characterized in that the feeder means for feeding the inside volume (42) of the casing (30) consist in a tubular element (38, 54, 56) made of insulating material.
