An arc chute for a circuit breaker includes a plurality of arc splitter plates 2, each plate having a pair of spaced parallel limbs 4,6 merging into a block portion. The arc chute also includes a pair of insulating barriers each containing a row of spaced channels arranged normally to a major longitudinal edge of the barrier, each channel encompassing one of the limbs 4,6 of each of the arc splitter plates. The insulating barriers may include a plurality of insulating members 12 each member having a protruding platform 28 and a stepped recess 17 such that two similar members may be engaged by superimposing one with the other with the protruding platform 28 of one engaging the stepped recess 17 of the other so as to provide a channel. The arc chute also includes a pair of arc conductors 32 which extend axially in register with respect to each other intermediate the barriers.
An arc chute for a circuit breaker including a plurality of arc splitter plates each plate having a pair of spaced parallel limbs merging into a block portion, a pair of spaced apart insulating barriers each barrier containing a row of spaced parallel channels arranged normally into a major longitudinal edge of the barrier each channel encompassing one of the limbs of each of the arc splitter plates, the block portions thereof extending intermediate the barriers, and a pair of arc conductors traversing the block portions of the arc splitter plates adjacent the end portions of the barriers and extending axially in register with respect to each other intermediate the barriers.
