消弧装置。[Claims for Utility Model Registration] (1) An arc extinguishing device for a circuit breaker, which is disposed facing a pair of switching contacts and extinguishes the arc that occurs between the switching contacts when the current is interrupted. wherein a plurality of approximately U-shaped arc extinguishing plates each having an opening on the opening/closing contact side are held in a stacked relationship with a space therebetween, wherein the thickness is reduced at the inlet portion of the arc extinguishing device; 1. An arc extinguishing device for a circuit or breaker, characterized in that an insulating plate made of a resin material that is enlarged toward the back is provided inside at least one of the legs of the arc extinguishing plate. (2) The arc extinguishing device for a circuit or breaker according to claim 1, wherein the thickness of the insulating plate increases linearly from the inlet of the arc extinguishing device toward the back. (3) The arc extinguisher of a circuit breaker or disconnector as set forth in claim 1 of the utility model registration claim, characterized in that the thickness of the insulating plate is gradually increased from the inlet of the arc extinguisher toward the back. Device.
