Abstract: A relay includes: a housing, a base plate, and a driving device, connected to the base. At least one stationary contact group is provided on the housing. The stationary contact group includes two stationary contacts insulated from each other. At least one stationary contact in the stationary contact group includes an upper terminal and a lower contact are included. The upper terminal and the lower contact are isolated from each other and electrically connected by a fuse. The base plate is provided in the housing and can switch between on and off positions. The base plate, when being in the on position, contacts the stationary contact group for the electrical conduction of the two stationary contacts in the stationary contact group, and, when being in the off position, is isolated from the stationary contact group for disconnecting the electrical conduction of the two stationary contacts in the stationary contact group.
