ABSTRACT:
An arc chute assembly for a circuit breaker or similar device comprising a series of metallic arc chute plates that are locked in stacked spaced-apart relationship between a pair of insulative side panels by elongated key members of non-conductive material that are wedged between the flat surfaces of the side panels and notched portions of pairs of T-shaped tabs which extend from each side edge of the respective plates. The tabs interlockingly engage a series of laterally-extending slot openings in the side panels in such a manner that the key members are in press-fitted engagement with only one of the tabs in each pair of tabs.
