A circuit breaker mounting base with strong stability is used in the processing of wear-resistant and anti-static plastic products. The anti-wear pad can protect the connection between the slider and the slide bar from being worn out due to long-term sliding, and protect the slider to prolong its service life. Improve the effect of shock absorption and buffering, so that the circuit breaker body is not easily affected by the impact force during operation, and the stability of its working state is improved
