[0003] A Chinese patent with publication number (CN217114276U) discloses a distribution circuit breaker, including a distribution circuit breaker body and an opening and closing switch, the opening and closing switch is installed and fixed at the middle position of the front end of the distribution circuit breaker body, an inner buckle plate is arranged on the inner side of the rear end of the distribution circuit breaker body, a lower connection screw is arranged on the inner side of the lower end of the distribution circuit breaker body, an upper connection screw is arranged on the inner side of the upper end of the distribution circuit breaker body, a limited storage frame is arranged on the distribution circuit breaker body above the opening and closing switch, and a transparent viewing plate is arranged on the inner side of the front end of the limited storage frame. The distribution circuit breaker disclosed in the utility model has a limited storage writing paper, which makes it more convenient to check and identify the control at a later time.

[0004] The defect of the above-mentioned selected technology is that a limited storage frame is installed on the front of the distribution circuit breaker body to store writing paper, and a paper storage slot is opened on the side of the limited storage frame, so that the writing paper can be inserted into the limited storage frame through the paper storage slot. However, because the opening of the paper storage slot is open, and the circuit breaker is generally installed in a distribution box for use, there will be vents on both sides of the distribution box and the distribution box also has a door gap. In humid weather, the humidity in the air will be very high, and the humid air will enter the limited storage frame from the paper storage slot to wet the writing paper, causing the writing paper to be damaged.
