Tips: Can I Use AC Circuit Breaker for DC?

The signal of AC current is constantly changing its value for every second. The circuit breaker arc will be extinguished at 0 volts, and the circuit will be protected from big current. But the signal of DC current is not alternating, it works in a constant state, and the voltage value will only change when the circuit is tripped or the circuit is reduced as a certain value. Otherwise, the DC circuit will provide a constant voltage value for every second of a minute. Therefore, since there is no 0 volt point in the DC state, it does not suggest that use a AC circuit breaker for the DC state.
