摘要： A molded case for a miniature circuit breaker provides a base and a cover whose outer mating peripheral walls, which form and enclose a cavity for housing a circuit breaker mechanism, have approximately equal widths, except for the projected handle area. In this handle area, the width of the peripheral wall of the base is increased and contains an aperture for receiving the handle, and the width of the peripheral wall of the cover is decreased to receive the increased aperture area of the base. This arrangement provides for full handle support in the base for ease of assembly; high ribbing for maximum strength for short circuits; and a minimum overall thickness of about 0.500 inches.
