More Information
Summary:An object is to eliminate, through an inexpensive structure, degradation in withstand voltage performance and degradation in energization performance caused by heating in a vacuum circuit breaker. The vacuum circuit breaker includes a main circuit structure body having an insulation rod (6), a vacuum switch (8), a movable side terminal (7a), and the like and an insulating holder (1) for supporting the main circuit structure body. The insulating holder (1) is a frame structure body having opening portions (5a, 5b, 5c, 5d) in the top and bottom surfaces and both side surfaces of the section in which the vacuum switch (8) is disposed and the section in which the insulation rod (6) is disposed.
