Abstract:
The invention relates to a mechanical assembly for a wire-fuse circuit-breaker (1) provided with a fuseholder (2) and a drive lever (3) adapted to be actuated by an operator and to actuate a lever for breaking the fuse wire.According to the invention, the direction of pivoting of the drive lever is the opposite of the direction of pivoting of the fuseholder tube and the mounting of the parts leaves sufficiently clear the area in the vicinity of the open lower end of the fuse-holder tube to allow gases produced by breaking the fuse wire to exhaust without disturbing the flow thereof. This makes a wire-fuse circuit-breaker safe to drive and safe in operation. The invention also relates to a method of renovating an existing wire-fuse circuit-breaker.
