The utility model discloses a combined mutual inductor voltage part low-voltage side output structure for an outdoor pole-mounted circuit breaker, a combined mutual inductor voltage high-voltage resistor R1 is poured in a pouring body, a voltage part low-voltage side secondary resistor R2 and a secondary capacitor C are welded on an adjusting circuit board, the adjusting circuit board is assembled in a bottom adjusting groove, and a voltage part low-voltage side secondary resistor R2 and a secondary capacitor C are welded on the adjusting circuit board. And then the secondary voltage signal is transmitted through the secondary voltage signal transmission line. According to the utility model, the process requirements of the product production process are reduced. And unqualified product scrapping caused by process discreteness is avoided. The measurement precision is adjustable, and the requirements of different loads can be met. The product qualification rate is improved, and energy conservation and consumpti
