Abstract
An arc-suppressing apparatus for a circuit breaker has a pair of side plates having a plurality of first and second grooves formed therein, the second grooves being shallower than the first grooves and extending linearly from the ends of the first grooves to an end of each of the side plates. The side plates are separated by a spacing strut and loosely connected by a bolt and nut so that a space exists between the plates which is large enough to allow a plurality of grids to slide along the second grooves into the first grooves. Thereafter, the nut and bolt are tightened to firmly secure the grids in the first grooves.
