The classification and main uses of circuit breakers are shown in the table
| Name | Current the type and scope of the | protection characteristics | The main purpose | 
| with electric circuit breaker | AC 200 ~ 4000A | instantaneous delay | do power The total electrical switches and branches near the switching source | 
| DC 600 ~ 6000A | long delay, instantaneous | is protected with the silicon rectifying DC device | |
| motor protection circuit breaker | AC 63 ~ 630A | instantaneous overcurrent trip multiple 8 ~ 15IN | motor protection | 
| is protected by a circuit breaker wire | AC 6 ~ 125A | overload long delay, instantaneous short circuit | for domestic buildings and secondary signals circuit | 
| breaker with leakage protection | AC 20 ~ 63A (home) AC 20 ~ 630A (industrial) | drain operation sensitivity Press the purpose of use stepper | to ensure personal safety, to prevent leakage fire |
