Identifying Circuit Breaker Faults

Identifying Circuit Breaker Faults

The following indicate that the circuit breaker is faulty:

  • The circuit breaker cannot be switched to ON/OFF after the short circuit fault for its end circuit is rectified.
  • When the circuit breaker is switched to ON and its input voltage is normal, the voltage between the two ends of the circuit breaker exceeds 1 V.
  • The input voltage is normal, but the resistance between both ends of the circuit breaker is less than 1 kΩ when the circuit breaker is OFF.
