Zusammenfassung:PURPOSE:To simplify wiring and assembly work, regarding a plug-in earth- leakage circuit breaker having a plug as integral part thereof for insertion in a receptacle. CONSTITUTION:The blade 9 of a plug 8 is extended and, then, the extended section 9b of the blade 9 is made to penetrate ZCT 4 as a primary conductor, thereby eliminating the need of separately connecting a lead wire to the blade 9. Also, a main circuit printed board 6 having a relay for opening and closing a main circuit led from the plug 8 to a load side terminal 11 is laid, and this board 6 and the section 9b are connected to each other with a connecting conductor 10 made of a molded conductor. In addition, an amplifier circuit printed board 7 to amplify output from the ZCT 4 and drive the relay, and the load side terminal 11 are connected to the main circuit printed board 6. According to this construction, each section can be mechanically fastened and electrically connected concurrently.
