摘要： The invention relates to an automatically quenching surge arrester arrangement with a surge arrester, which, on exceeding a given first voltage, transforms from a non-conducting into a conducting state and returns to the non-conducting state only when a much smaller second voltage is dropped below and with a switch mechanism reacting to current flow through the surge arrester, interrupting the current flow through the surge arrester and then automatically returning to the rest condition thereof. A simple, robust and compact assembly suitable for HF applications for such a surge arrester arrangement is achieved, whereby the switch mechanism reacts reversibly to the heat generated in the surge arrester by the current flow.
