Outdoor vacuum circuit breaker

The utility model provides an outdoor vacuum circuit breaker. The outdoor vacuum circuit breaker comprises a circuit breaker body; the inlet wire contact is arranged on the circuit breaker body and is suitable for fixing an inlet wire cable, and a bimetallic strip is arranged on the inlet wire contact; the indicating rod is installed on the wire inlet contact in a vertically movable mode through an elastic piece, the indicating rod is provided with a locking position locked by the bimetallic strip and an indicating position separated from the bimetallic strip and popped up, and the elastic piece is suitable for applying elastic acting force moving towards the direction of the indicating position to the indicating rod. Therefore, when the current load is too large, the bimetallic strip is deformed due to the temperature rise of the incoming line contact, so that the bimetallic strip is separated from the indicating rod, the indicating rod is ejected upwards under the elastic acting force of the elastic piece,
