<p>A cassette assembly for rotary contact circuit breakers utilizing a first electrically insulative cassette half piece (14) and a second electrically insulative cassette half piece (60) which are arranged to mate with each other to form an enclosure. The electrically insulative cassette half pieces (14, 60) include improper installation rejection features for both the rotor (37) and arc chute assemblies (20, 22). The inner surface (52, 62) of an electrically insulative cassette half piece (14, 60) including a groove (58) and recesses (54, 56, 64, 66) formed therein. A rotor (37) is properly positioned within the electrically insulative cassette half piece (14, 60) by inserting a pin (114) on the face (19) of the rotor (37) into the groove (58). An arc chute assembly (20, 22) is properly positioned within the electrically insulative cassette half piece (14, 60) by inserting a tab (80) located on a side member (70, 72, 82, 84) of the arc chute assembly (20, 22) into a corresponding recess (54, 56, 64, 66) located in the electrically insulative cassette half piece (14, 60).</p> |
