| Summary: | Disclosed are a position indicating apparatus for a circuit breaker and a circuit breaker having the same. The circuit breaker having a position indicating apparatus comprises a cradle having a bus bar terminal and a load terminal; a main body having a bus bar connection unit and a load connection unit respectively connected to the bus bar terminal and the load terminal, and configured to be movable to a run position that the terminals and the connection units are connected to each other, and to a test position that the terminals and the connection units are separated from each other; and a position indicating apparatus configured to outwardly display a position of the main body by interworking with motion of the main body, wherein the position indicating apparatus comprises: a movable pin interworking with motion of the main body; and a display unit configured to display a position of the main body corresponding to a position of the movable pin by interworking with motion of the movable pin. Accordingly, the position of the main body of the circuit breaker can be intuitively checked rapidly and precisely. |
