ABSTRACT:
An arc chute for circuit interrupting devices comprises a series of identical arc plates, each having a pair of opposed, laterally extending tangs which fit through slots in insulative sideplates. The tangs are undercut to provide notches in which the sideplates are engaged when the arc plates are bodily shifted to locked positions with the tangs latched in the sideplate slots. An insulative backplate captured in slides in the sideplates engages the arc plates to sustain their locked positions.
