Claims

[Scope of utility model registration request]

A movable contact rod has a movable contact attached to one end that connects and separates from the fixed contact, an overcurrent response mechanism that operates when an abnormal current flows through both of the liquid contactors, and an overcurrent response mechanism that is activated by the operation of this response mechanism. In the circuit breaker, the circuit breaker is equipped with an exception lever that opens the movable contact when the movable contact is opened, and a casing in which these are housed, a second casing arranged in parallel with the casing, and a second casing inside the second casing. 1. An alarm device for a circuit breaker, comprising: an alarm switch provided in a circuit breaker; and an interlocking element that operates the switch in response to the opening operation of the movable contact of the exception rod.
