The present invention relates to a circuit breaker, and more specifically, to a circuit breaker comprising: a case; a terminal unit in which a power side terminal or a load side terminal is inserted and connected; and a terminal cover inserted and installed between edges of a side wall of the case, and covering an opening unit formed in the terminal unit. The terminal cover comprises: a first surface part mounted and combined between edges of the side wall of the case to face an insertion direction of the power side terminal or the load side terminal; a second surface part mounted and combined between edges of the side wall of the case to face the insertion direction of a driver to bind the power side terminal or the load side terminal, and having a driver insertion hole; and a discharge hole formed to be communicated with the inside of the terminal unit in the second surface part. Accordingly, human body can be prevented from electric shock, and heat generated in the terminal cover can be smoothly discharged through the discharge hole. |
