| 摘要 | A monitor circuit is provided which detects various incipient failure modes of a circuit breaker. The monitor circuit includes a processor and a primary circuit connected in circuit with the processor. The primary circuit may be configured for preventing transients and high currents associated with the operation of the circuit breaker from damaging the processor. A secondary circuit may be connected in circuit with the processor and the primary circuit. The secondary circuit provides an analog voltage input and a current input to the processor that is representative of an aspect of the circuit breaker and wherein the processor is configured to detect at least one failure mode of at least one circuit breaker from the analog voltage and current input. | ||||||
