The invention relates to the technical field of electric leakage circuit breakers, in particular to a modular plastic shell type electric leakage circuit breaker. The circuit breaker comprises an electric leakage circuit breaker body, and the electric leakage circuit breaker body comprises a switch module and an electric leakage grounding fault detection module electrically connected with the switch module; the electric leakage grounding fault detection module comprises an upper seat and a lower seat, wherein the upper seat and the lower seat are correspondingly arranged up and down, the upperseat is provided with a plurality of plugging guide rails, and the plurality of plugging guide rails are arranged side by side at intervals; the bottom of the upper seat is provided with a first groove used for placing a current transformer, and one side of the first groove is provided with a second groove used for placing a circuit board. According to the invention, a pluggable design is firstlyadopted, so the installation is convenient; then the circuit board and the current transformer are designed into independent structures, so the overall safety performance of the product is greatly improved, the manufacturing is simple, and the implementation is easy; and finally, the buttons are designed in rows, so the misoperation phenomenon of a user in the use process is prevented.
Description
technical field [0001] The invention relates to the technical field of earth leakage circuit breakers, in particular to a modular plastic shell type earth leakage circuit breaker. Background technique [0002] At present, with the continuous development of society, the requirements for leakage circuit breakers are getting higher and higher, and its protection modules with comprehensive functions and small size are inevitable development trends. Due to the unreasonable design of the existing earth leakage circuit breaker, the size of the product is enlarged, the use is cumbersome, and the overall safety performance is poor. [0003] For example, the Chinese invention patent, application number: 201620915554.9, discloses a four-pole plastic case circuit breaker. The above-mentioned technical solution has a complex structure, cumbersome manufacture, and is not easy to implement. [0004] Therefore, in order to thoroughly solve the problems existing in the prior art, the presen...
