The utility model discloses a small-sized residual current circuit breaker, which comprises a circuit breaker body and a label plate; the label plate includes the bottom plate and is used for writing the cardboard of mark, the bottom plate is installed at the leading flank of circuit breaker body, and the left and right sides limit portion of bottom plate embraces forward and detains and form the slot, the cardboard cartridge is in the slot of bottom plate, and the cardboard middle part can be used for writing corresponding mark content, for example refrigerator, air conditioner, washing machine etc. can audio-visual demonstration circuit breaker controlled circuit, and the writability of cardboard is splendid to can change as required, the sign on the cardboard can be handwritten or printed and go, all can reach the utility model aims at.

Furthermore, the label plate also comprises a transparent panel, the transparent panel and the paperboard are mutually overlapped and inserted into the slot of the bottom plate, and the transparent panel covers the outer side of the paperboard and plays an effective protection role in the paperboard so as to be beneficial to long-term use.

Further, the bottom plate is the metal material, and the leading flank of circuit breaker body is fixed with and is used for adsorbing fixed magnetic path to the bottom plate, utilizes magnetic adsorption to paste the dress on the circuit breaker body with the bottom plate, conveniently gets and changes in the dress, and magnetic force has certain application range, when the circuit breaker body sets up the apron because of the surface and is blocked, also can utilize magnetic adsorption to paste the bottom plate on the apron.

Further, the magnetic block is embedded into the shell fixed on the circuit breaker body, and the magnetic block is embedded into the shell in the production process of the circuit breaker body, so that the appearance of the circuit breaker is not affected, and the performance is superior.

Furthermore, the transparent panel is made of plastic, and the structural strength can meet the requirements.

The utility model has the advantages that: the utility model discloses a small-size electric leakage circuit breaker has adopted the tag board of normalization, compares with prior art, can carry out effectual mark according to actual conditions, and the mark is clear, clear and definite, and changes the convenience, does benefit to the discernment.
