Summary:An improved circuit breaker and arc chute has a shield apparatus that includes a number of plate-like shield members that have elongated openings formed therein to receive portions of arc plates therethrough. The portions of the arc plates that pass through the shield member are received in receptacles of a support apparatus that supports the arc plates. The arc plates are themselves configured to retain the shield members against the support apparatus to protect the support apparatus from damage in the event of an electrical arc. Advantageously, the retention of the shield members between portions of the are plates and portions of the support apparatus enables the shield members to be held in place without the use of adhesives or separate fastening systems. Un disjoncteur amélioré et une cage de soufflage comportent un appareil de protection qui comprend plusieurs éléments protecteurs de type plaque qui présentent des ouvertures allongées intégrales servant à recevoir des portions de plaques darc les traversant. Les portions de plaques darc qui traversent lélément protecteur sont reçues dans les réceptacles dun appareil de support qui supporte les plaques darc. Les plaques darc sont elles-mêmes configurées pour retenir les éléments protecteurs contre lappareil de support afin de protéger lappareil de support des dommages dans léventualité dun arc électrique. Avantageusement, la rétention des éléments protecteurs entre les portions des plaques darc et des portions dappareil de support permet aux éléments protecteurs dêtre maintenus en place sans adhésif ou système de fixation séparé.
