Abstract
The present disclosure provides a surge protection device comprising a surge arrestor and an arrestor assistor. The surge arrestor is arranged within a circuit branch connected in parallel with a load and adapted to clamp a load voltage to a clamping voltage not larger than a load voltage limit when the load voltage rises to a breakdown voltage of the surge arrestor, the breakdown voltage increasing with a rising rate of the load voltage. The arrestor assistor is connected in parallel with the surge arrestor within the circuit branch and adapted to make the load voltage rise to the breakdown voltage not larger than the load voltage limit. The present disclosure also provides a telecommunication equipment comprising the surge protection device.
