DPS - Surge Protection Device

DPS - SURGE PROTECTION DEVICE


The surge protective devices (SPD) are used to protect electrical circuits against voltage surges from lightning (lightning) or surges caused by switching loads such as a contactor turning on or off an engine. Currently, with more and more electrical equipment connected to the power grid and in a country with a high incidence of lightning, the use ofSPD is increasingly important. The DPS2 line containing unipolar, bipolar and three-pole models with maximum voltage continues 415VAC, protective voltage level (Up) of 1.7kV nominal discharge current of 20kA (8 / 20µs) and maximum discharge current of 45kA (8 / 20µs). They are type II and their application is basically in control cabinets, homes, and other electrical installations.
