The current detecting mechanism is used to control the breaker mechanism which includes a separated elastic member driving the moving contact to descend, and the reset mechanism includes a reset column, a connecting member, a first reset elastic member, a moving seat, and a second reset elastic member. The separated elastic member is coupled to the connecting member through the moving seat, and the reset column has a latch groove for latching the connecting member. The breaker mechanism is used to drive the connecting member to retreat from the latch groove, and the second reset elastic member is used to drive the reset column to ascend. After the reset column descends, the first reset elastic member drives the connecting member to be latched into the latch groove to miniaturize the electric leakage protector.
