<P>PROBLEM TO BE SOLVED: To provide a plug-in circuit breaker which excels in assembly workability and exhibits high contact reliability. <P>SOLUTION: The plug-in circuit breaker comprises a circuit breaker body provided with a screw connection terminal and a plug-in adapter which is connected with screws to the circuit breaker body. The plug-in adapter incorporates in a plug case a plug-in terminal into which one of a plurality of bus bars is inserted for connection, a plug holder which is mechanically connected to the circuit breaker body, and a shunt conductor which electrically connects the plug-in terminal and the circuit breaker body. The plug-in terminal is provided with a pair of concavities which are formed as an integral body. The plug holder is provided with a plug-in terminal attachment part consisting of an opening having a salient loosely fitted thereto for positioning the plug-in terminal and holding it therein. The plug-in terminal is disposed to be able to turn around the salient at a certain angle relative to the horizontality of the opening provided in the plug holder. <P>COPYRIGHT: (C)2013,JPO&INPIT |
