Abstract
A description is given of a switching device, comprising a circuit-breaker means 3 connected in parallel with a varistor 5; the threshold voltage (Vt) of the varistor 5 is selected in such a way that the voltage across the terminals of the circuit-breaker means 3, when the latter is non-conducting, is always less than the maximum value V0 of the acceptable voltage across the terminals of the said circuit-breaker means 3.
