Abstract

The utility model discloses a breaker electric leakage module, which comprises a leakage current trigger structure and a reset button, the leakage current trigger structure comprises a support, a movable feeler lever and a movable iron core, the movable feeler lever and the movable iron core are arranged on the support, and the movable feeler lever is movably arranged on one side of the movable iron core in the action direction within a set range. And one end of the reset button is connected with the movable feeler lever. According to the utility model, the electric leakage module structure independent of the circuit breaker is adopted, the combination of the leakage current trigger structure and the reset button is arranged in the electric leakage module structure, the complexity of the structure is effectively reduced, the transmission action when the leakage current is triggered in an abnormal state is simplified, and the reset operation after triggering by a user is greatly simplified due to the arrangement of the reset button; according to the utility model, the internal trigger structure can be linked through the pressing action of the reset button without extra tedious dismounting work, and the user can know the current state of the circuit breaker more clearly through the setting of the reset button.
