The products of the range DS250VG is an extreme duty Type 1+2+3 AC surge protector device designed to protect at the entrance of the electrical installation. This SPD is particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (eg: buildings equipped with lightning rods). The `Spark gap + Varistor` technology allows a very low level of protection and an absence of following current. The DS250VG is mounted on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.
