A plastic-shell-encased circuit breaker having an automatic locking function comprises a plastic-shell-encased circuit breaker body comprising: a user input unit (11) for inputting a lock code or an unlock code; an authentication processing unit for receiving the lock code or the unlock code from the user input unit, and for outputting a control signal upon authentication; and a locking action unit for receiving the control signal from the authentication processing unit, and for enabling the plastic-shell-encased circuit breaker body to produce a locking or unlocking action. Use of said plastic-shell-encased circuit breaker having an automatic locking function prevents the circuit breaker from being switched on without careful consideration, thereby ensuring operator safety. |
