摘要

The circuit breaker box 1 includes a housing unit that can house therein a switching device 11 that switches contacts and a conductor 20 that is connected to the switching device 11. The housing unit has a tubular shape extending in a first direction and that includes: a horizontal top surface 2; inclined surfaces 3 extending downward from both sides of the top surface 2 so as to be away from each other; a bottom surface 4 that opposes the top surface 2; and side surfaces 5 perpendicularly extending from both sides of the bottom surface 4 towards the inclined surfaces 3. The circuit breaker box 1 further includes fins 12, 13 that are provided upright on the top surface 2 and on the inclined surfaces 3.
