Abstract: The purpose of the invention is to create such a varistor fuse element, which should within a single housing include both a varistor (1) as well as an electric fuse (2), wherein said varistor part i.e. a varistor (1) is intended to protect each electric installation against overvoltage impulses and consequently against current strokes, while the fuse (2) is capable to transmit the current stroke due to increased voltage and to interrupt each permanently increased electric current, which might occur due to defects on the varistor (1). Moreover, such varistor fuse should not exceed dimensions of already known and widely used protective means, in particular melting fuses. In accordance with the invention, the fuse (2) with its round tubular casing (20) and the varistor, which is also embedded within a round tubular casing (10), are serial interconnected and arranged coaxially within each other.
