PROBLEM TO BE SOLVED: To provide a handle lock member for a circuit breaker capable of making a display means for a contact position visible from the outside and surely holding a handle lock state while securing easiness in attachment to and detachment from an operation handle of the circuit breaker regardless of whether the operation handle is located at a closing position or an opening position.MEANS FOR SOLVING THE PROBLEM: The handle lock member is configured to fix an operation handle member in the circuit breaker into a contact open state where the operation handle falls down from a body of the circuit breaker and a contact closed state where the operation handle falls down onto the body. The handle lock member is formed by connecting a first frame part that the falling-down operation handle member penetrates, and a second frame part for exposing an opening/closing indication that indicates the open state or the closed state outside of the body. Further, the handle lock member is provided with a concealing part for covering and concealing a leakage test button that is provided in the circuit breaker.SELECTED DRAWING: Figure 1 |
