PROBLEM TO BE SOLVED: To provide a ground leakage breaker capable of minimizing the operating force of an operation handle by automatically performing, at actuation of an electromagnetic tripper, resetting of the tripper interlocked with interrupting operation of an opening and closing mechanism part. SOLUTION: This ground leakage breaker comprises a reset arm part 6d protrusively formed on a tripping plate 6 of the release-type electromagnetic tripper 1. When the tripper 1 is actuated to make the opening and closing mechanism part take the interrupting operation, a protruding portion 8a of a separator 8 of the mechanism part is engagingly locked by the reset arm part 6d, and is moved to a reset position in interlocking with rotating operation of the separator 8, whereby the tripper is reset.
