Abstract
The utility model belongs to the home-use leakage circuit breaker. The utility model in particular relates to a lightning-proof surge current home-use leakage circuit breaker. The utility model comprises a leakage protector 1 and a lightning-proof module 2. The leakage protector 1 comprises a base frame 11 and connecting terminals 12 and 13. The connecting terminals 12 and 13 are provided on the base frame 11. At least one lightning-proof module 2 is arranged in the leakage protector 1. One end of the lightning-proof module 2 is connected with the connecting terminals 12. The other end of the lightning-proof module 2 is connected with the connecting terminals 13. The lightning surge or the switching surge of the household power source coil-in terminal is able to be cut off or bled off. The damage of the household electrical appliances caused through the lightning surge or the switching surge is avoided. The ability of absorbing the lightning surge and the switching surge is strong. The utility model has the advantages of low limited voltage, fast speed of response and no follow current. The frequent misoperation of the home-use leakage circuit breaker caused through the lightning surge or the switching surge is effectively reduced.
