Claims

[Claims for Utility Model Registration] 1. A support glass provided with a pair of fixed contacts on the power supply side and a load side, with a charging side electrode at one end facing one of the fixed contacts, and a pair of fixed contacts on the other side. A first non-linear resistance element having an intermediate electrode at the other end facing the child and a first non-linear resistance element having one end thereof are connected in series with each other via the intermediate electrode, and the other end 1. A fuse holder with a built-in lightning arrester element, characterized in that a second non-linear resistance element having a ground side electrode is embedded opposite to the base metal fitting of the supporting glass. 2. In practical use, the charging side electrode and intermediate electrode of the first nonlinear resistance element and the fixed contact, and the grounding side electrode of the second nonlinear resistance element and the base metal fitting are connected by conductors, respectively. A fuse holder with a built-in lightning arrester element as claimed in claim 1. 3 A discharge gap is provided between at least one of the charging side electrode and intermediate electrode of the first nonlinear resistance element and the fixed contact, and the grounding side electrode of the second nonlinear resistance element and the base metal fitting are separated from each other. A fuse holder with a built-in lightning arrester element according to claim 1, which is connected directly or indirectly through a series discharge gap.
