[0035] When the utility model is in use, the circuit breaker is installed inside the protection device body 1, thereby achieving sealed protection for the circuit breaker and preventing the circuit breaker from being affected by moisture and water. When both sides of the circuit breaker need to be wired, the sealing component 3 is opened, and the wires are inserted into the circuit breaker.
