摘要： A circuit breaker can minimize a change in a structure of a case when a material forming a stud is changed. A stud includes a base portion provided in the case and a protruding portion protruding from the case. A cross-sectional area of the protruding portion is more than that of the base portion; thereby a thermal conductivity of the protruding portion increases and the thermal conductivity from the protruding portion to an external conductor connected to the stud increases. In addition, since a surface area of the protruding portion increases, an amount of heat dissipated from the protruding portion increases. In the invention, since dimensions of the base portion inserted into a stud insertion hole of the case are not changed, it is not necessary to change the dimensions of the insertion hole of the case.

摘要： Provided is a circuit breaker capable of minimizing a change in the structure of, for example, a case even when a material (thermal conductivity) forming a stud is changed.A stud (20) includes a base portion (21) that is provided in a case (2) and a protruding portion (22) that protrudes from the case (2). The cross-sectional area of the protruding portion (22) is more than that of the base portion (21). When the cross-sectional area of the protruding portion (22) is more than that of the base portion (21) in the stud (20), the thermal conductivity of the protruding portion (22) increases and it is possible to increase the thermal conductivity from the protruding portion (22) to an external conductor connected to the stud. In addition, since the surface area of the protruding portion (22) increases, the amount of heat dissipated from the protruding portion (22) increases. In this case, since the dimensions of the base portion (21) inserted into a stud insertion hole (2b) of the case (2) do not vary, it is not necessary to change the dimensions of the insertion hole (2b) of the case (2). Therefore, it is possible to minimize a change in the structure of a component even when the material forming the stud is changed.

摘要： A terminal covering cap is mounted over the connection terminals of a multi-phase electrical switching device in order to increase the electric strength between the connection terminals of neighbouring phases. The L-shaped terminal covering cap closely abuts on its side facing the insulating housing the marginal region of connection openings leading to the connection terminals, with a negligible air gap. With this barrier, the required increased test voltage between the connection terminals can be withstood. On the side facing away from the insulating housing, the terminal covering cap is provided with ribs, to extend the creep distance on this side of the terminal covering cap. The terminal covering cap formed in this way makes it possible to carry out testing a the prescribed, increased test voltage without enlarging the insulating housing in order to extend the creep distance between the connection terminals of neighbouring phases.
