Summary:A mechanical loop power-off structure of earth leakage circuit breaker is applied in a single-phase two-pole earth leakage circuit breaker. The earth leakage circuit includes an L-pole circuit breaker and an N-pole circuit breaker. The L-pole circuit breaker and the N-pole circuit breaker are respectively disposed with a mechanism component, a return lever, and a handle therein. The handle serves as a switch of the earth leakage circuit breaker. The L-pole circuit breaker is also disposed with a loop component. The N-pole circuit breaker is also disposed with a contact terminal and a circuit board. The mechanical loop power-off structure of the earth leakage circuit breaker includes a power flat spring, wherein one end of the power flat spring is disposed on the circuit board while the other end of the power flat spring is connected to the contact terminal; a conductive post, wherein one end of the conductive post is disposed on the circuit board, and the other end of the conductive post is disposed with an e
