Electronic trip protector

The invention provides an electronic trip protector, belonging to the field of electronic devices. The electronic trip protector is used in a circuit breaker and comprises a base, a manual trip piece,a first control mechanism, a plug wire trip piece, a plug wire action piece, and a second control mechanism, wherein when the manual trip piece keeps in a first state, the plug wire trip piece controls the circuit breaker to keep in a non-tripping state, when the manual trip piece keeps in a second state, the plug wire trip piece controls the circuit breaker to keep in a tripping state, when a second control mechanism blocks a plug wire port, the second control mechanism controls the plug wire action piece to keep in a third state, when the second control mechanism is far from the plug wire port, the second control mechanism controls the plug wire action piece to keep in a fourth state, when the plug wire action piece keeps in the third state, a first limit part and a second limit part leave each other, when the
