    摘要: A position switch and a circuit breaker having a position switch are provided. Contact plates, each having an elastically variable height, may be provided between switch blocks and switch levers. A testing contact plate and a running contact plate may compensate for inferior dimensioning of the switch blocks and the switch levers. Such a configuration may allow a position of a breaker body to be quickly and accurately displayed and, further, may prevent damage of the position switch provided at the breaker body. Furthermore, such a configuration may prevent any connection inferiority between a terminal of the breaker body and a terminal of a cradle.

    摘要: Disclosed are a plug interlock device for a circuit breaker and a circuit breaker having the same, wherein a plug is not allowed to be separated from a connector while a breaker main body is moved from a test position to a run position or is running at the run position, thereby obviating the plug from being unexpectedly unplugged from the connector while the breaker main body is moved from the test position to the run position or is running, resulting in preventing a safety accident in advance.

    摘要: Disclosed are a position switch and a circuit breaker having the same. As contact plates having an elastically variable height are provided between switch blocks and switch levers, each of a testing contact plate and a running contact plate may compensate for inferior dimensioning of the switch blocks and the switch levers. This may allow a position of a breaker body to be rapidly and precisely displayed, and may prevent damage of the position switch provided at the breaker body. Furthermore, connection inferiority between a terminal of the breaker body and a terminal of a cradle may be prevented.
