Small-sized circuit breaker by remote control

The invention relates to a small-sized circuit breaker by remote control. In the prior art, when a present small-sized circuit breaker by remote control is tripped, there is an induced voltage at a load end of the circuit breaker, so that the circuit breaker has poor safety performance. However, the above-mentioned problem can be solve by utilizing the small-sized circuit breaker by remote control provided in the invention. The circuit breaker is characterized in that: a control circuit board (4) is provided with a terminal (9) that has a jack (8) in the middle of the terminal; the terminal (9) is a connection point of phase lines; a bent steel wire (16) is arranged between an N-electrode circuit breaker (1) and a P-electrode circuit breaker (2); one end of the steel wire (16) passes through a through hole (11) and is inserted into the jack (8) of the terminal (9); and the other end of the steel wire (16) passes through a small hole (13) and is suspended between a moving contact (14) and a fixed contact (15),
