    • In one example embodiment of the present application, the switching device includes a first switching point for normal switching of at least one current path, and includes a second switching path for disconnection of a short-circuit current. The first and second switching points are connected in series, and are accommodated in a common enclosure. Electrical connections and, if required, a control connection for inputting a switching command, are provided in or on the enclosure for connection of the current paths. The first switching point is designed for a maximum continuous current. The second switching point is designed to disconnect a short-circuit current which is a multiple of the maximum continuous current. The first switching point includes at least one main contact which can withstand a short-circuit at least for the time by means of a contact holding system or a contact locking system.
    • 在本申请的一个示例实施例中,开关装置包括用于至少一个电流路径的正常切换的第一切换点,并且包括用于断开短路电流的第二切换路径。 第一和第二开关点串联连接,并容纳在共同的外壳中。 如果需要,电气连接和用于输入切换命令的控制连接被提供在外壳中或外壳上,用于连接当前路径。 第一个开关点设计用于最大连续电流。 第二个开关点设计用于断开短路电流,该短路电流是最大连续电流的倍数。 第一开关点包括至少一个主触点,其至少借助于触点保持系统或触点锁定系统至少可以承受短路。
