| 摘要 | A fault state indication device for a circuit breaker, comprising a contact group, a transmission assembly and an indication assembly which are mounted inside a housing. The contact group implements a normally open contact group and a normally closed contact group. The transmission assembly acts on a contact support (107), different open and closed states of the contact group are realized via the contact support. The indication assembly indicates a fault state, the indication assembly is linked with the circuit breaker, and carries out a corresponding state indication in response to a fault. The fault state indication device for a circuit breaker has a simple and reliable structure, a manufacturing process which is easier to implement. The fault state indication device can not only indicate the state and type of a load line failure, but also judge an operation state of the circuit breaker via the contact group. | ||||||
