回路遮断器。 In a circuit breaker equipped with an exhaust plate having an exhaust hole to exhaust the arc generated when the contacts open,
Grooves are provided on both sides of the inner surface of the housing into which both ends of an exhaust plate with an exhaust hole are inserted to support the exhaust plate, and flexible grooves are provided on both sides of the outer surface of the exhaust plate to cover the exhaust hole. An insertion piece to be inserted into the groove of the housing is formed from below the approximate center of the dust-proof plate on both sides, and a cut-and-raised piece is formed with a U-shaped cut extending downward from the approximate center of the dust-proof plate on the upper surface line of the insertion piece. A circuit breaker characterized in that the exhaust plate is provided with a locking hole in which the cut-and-raised piece is inserted and locked to support the dust-proof plate.
