Abstract
A miniature circuit breaker with two thermal-magnetic poles has an electronic trip device providing ground fault, and sputtering arc fault (if desired), protection located entirely in a large central compartment of a molded housing between compartments housing the two mechanical poles. The molded housing is assembled from a top base and top cover forming a compartment for the thermal-magnetic trip device of the first pole, and a bottom cover and a bottom base forming the compartment for the second mechanical pole. A hollow center piece mates with the top and bottom bases to form the single, large electronics compartment.
