Circuit breaker with alarm |
摘要 |
A circuit breaker and alarm device for a circuit having a series connected interruptible current device whereupon a circuit breaker tripping means, attached to said circuit breaker, is adapted to obtain an output voltage of one polarity upon the tripping of the circuit breaker. A circuit breaker resetting device, attached to said circuit breaker, is adapted to obtain an output voltage of reverse polarity upon the resetting of the circuit breaker. A voltage-detecting circuit for sensing the voltage produced by the tripping or resetting of the circuit breaker. A current detecting circuit which produces an output upon detecting an output produced by the voltage-detecting circuit. An alarm circuit which is connected to the current-detecting circuit is thereby caused to essentially instantaneously upon the tripping of the circuit breaker, to energize and remain energized until the resetting of the circuit breaker.
