Abstract:
An arc stack for receiving a circuit breaker blade moveable between a closed position and an open position, includes a plurality of generally rectangular are plates having substantially similar length and width dimensions and positioned substantially parallel to one another. The straight edges of the arc plates are in line with one another so that the are stack is generally rectangular in shape. The arc plates have respective arc throats formed therein having a plurality of sizes so as to form a longitudinal passageway extending through the arc throats following the arc generated by the blade moving between the closed and open positions. The arc plates include sets of arc plates with the arc plates in each set having identical arc throats. The sets of arc plates are arranged in order of decreasing arc throat size with the set having the largest arc throats being positioned adjacent the circuit breaker blade in the closed position. The arc stack is formed in two sections with each section including a selected number of arc plates. The arc plates in each section are interconnected by a pair of side fibers engaging associated edges of the arc plates. The two sections are connected to form the arc stack by engaging the inner edges of the pair of side fibers of one section with mating inner edges of the pair of side fibers of the other section.
