Abstract

PURPOSE:To visually detect the state that a current limiting element is short- circuited and the grounding current flows easily by providing a display means on an electrode forming a serial gap connected in series to the current limiting element via a melting portion melted by the grounding current. CONSTITUTION:A melting portion 2 melted when the grounding current flows is formed on an electrode section constituting the serial gap 4 of a horn device with no dynamic current constituted of a current limiting element 1 and the serial gap 4, and a display means 3 supported by this melting portion 2 is provided. When the normal thunderbolt surge current flows, the melting portion 2 is not melted, when the grounding current flows at the time of the short circuit of the current limiting element 1, the melting portion 2 is melted, and the display means 3 is removed. An abnormality can be thereby visually detected easily.
