<P>PROBLEM TO BE SOLVED: To provide a circuit breaker capable of supporting both "a surface connection type" and "a rear connection type" and obtaining a sufficient insulation distance. <P>SOLUTION: A circuit breaker includes an opening/closing mechanism which opens and closes current flowing to a cable run, a base which is formed of an insulation material and stores the opening/closing mechanism, a cover which is formed of the insulation material, covers the base, and constitutes an enclosure together with the base, and a connection terminal which is arranged in a terminal block of the base and connected to an external connection conductor. This circuit breaker is also provided with a backside stud mounting hole formed on the lower side of the connection terminal on the reverse side of the base, a through hole formed on the base so as to penetrate through the backside stud mounting hole and the surface of the terminal block, and an insulating block which is inserted to the through hole, is held by the base, and blocks the backside stud mounting hole. <P>COPYRIGHT: (C)2012,JPO&INPIT |
