摘要
A miniature circuit breaker (100) with a novel zero-sequence transformer installation structure, comprising an intelligent control module (10), a first circuit breaker (20), and a second circuit breaker (30) sequentially arranged side by side. The first circuit breaker comprises a first shell (29), an electric leakage protection module (22) provided in the first shell, a first incoming line terminal (21), a first outgoing line terminal (23), and a neutral line wiring board (24). One end of the neutral line wiring board is connected to the first incoming line terminal, and the other end penetrates through the electric leakage protection module and is connected to the first outgoing line terminal. The electric leakage protection module is connected to the intelligent control module. The second circuit breaker comprises a second shell (35), a current transformer (32) provided in the second shell, a second incoming line terminal (31), a second outgoing line terminal (33), and a live line wiring board (34). One end of the live line wiring board is connected to the second incoming line terminal, and the other end sequentially penetrates through the second shell, the first shell, the electric leakage protection module, and the current transformer and is connected to the second outgoing line terminal. The current transformer is connected to the intelligent control module. The miniature circuit breaker aims to optimize the structure of the circuit breaker, reduce the cost and decrease the volume.
