Circuit breaker |
摘要 |
A circuit breaker includes a main case; a switching mechanism accommodated in the main case, and having a mechanical part for opening and closing a circuit; a trip mechanism configured to trigger the switching mechanism to a circuit interrupting position upon detection of an abnormal current on a circuit; and an external device detachably mounted to the main case, wherein the circuit breaker includes an interrupting means configured to interrupt the switching mechanism by contacting at least a part of the external device when the external device is mounted to the main case. |

1. A circuit breaker, comprising:
a main case; a switching mechanism accommodated in the main case, and having a mechanical part for opening and closing a circuit; a trip mechanism configured to trigger the switching mechanism to a circuit interrupting position upon detection of an abnormal current on a circuit; an external device detachably mounted to the main case; a latch included in the switching mechanism, and configured to maintain a circuit connected state; a latch holder configured to restrict or release a movement of the latch; and a bracket rotatably mounted to the trip mechanism, and configured to restrict or release the latch holder according to a rotation direction, wherein the circuit breaker comprises an interrupting means configured to interrupt the switching mechanism by contacting at least a part of the external device when the external device is mounted to the main case, and wherein the interrupting means includes a protrusion portion integrally formed at the bracket, and an arm formed at the external device. |
