Abstract (en)

[origin: WO2017009355A1] The invention relates to a varistor (1) comprising a disconnecting device (A) which can interrupt the flow of current through the varistor (1) in case of a fault. The disconnecting device (A) includes a terminal contact (5) that establishes an electrical contact with a first terminal (2) of the varistor (1), the electrical contact being secured by a thermally softenable holding device (4). The disconnecting device (A) further includes a separating means (6) which is biased by an energy accumulator (7) and which, in case of a fault, mechanically separates the terminal contact (5) from the first terminal (2) of the varistor (1) when the thermally softenable holding device (4) softens. The separating means (6) is resistive in order to limit the current flowing through the varistor (1) and prevent electric arcs from forming.
