<p><P>PROBLEM TO BE SOLVED: To provide a circuit breaker and an adaptor for the circuit breaker which are not required to be installed at each of a plurality of bus bars constituting a bus bar group, which can be connected to an arbitrary bus bar in the bus bar group only by changing an insertion position of an insertion plug, which as a result can communalize a breaker for different connection systems such as single and three phase, etc.,, and which can achieve miniaturization and simplification of a distribution board, and cost reduction. <P>SOLUTION: A circuit breaker includes: overhanging blocks 5 which overhang from a breaker body part 2 to the side thereof and have a plurality of plug insertion holes 7; and conductive plugs 8 inserted into these plug insertion holes 7. Each of the plug insertion holes 7 is conductively connected to a cut-off circuit of the breaker body part 2, and the conductive plugs 8 selectively inserted into the plurality of the plug insertion holes 7 are connected to the corresponding bus bars 91 in the power source bus group. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
