| Zusammenfassung: | An object is to provide a switching unit or switching gear which enhances heat radiation performance and eliminates the need for an increase in unit size. In order to solve this problem the switching unit includes a switch and insulating resin located in a way to cover the periphery of the switch, in which the switch includes a fixed electrode, a movable electrode facing the fixed electrode and moving in an axial direction to contact or leave the fixed electrode, a bus side conductor connected to one of the electrodes and connected to a bus, and a load side conductor connected to the other electrode and connected to the load. The insulating resin has fins formed in a circumferential direction on the outer surface of the insulating resin and the distance between the periphery of the switch and the bottoms of the fins is almost constant in the circumferential direction. |
