Prosurge V50, DS50 and DT50 series SPD are certified by TUV as per IEC/EN 61643-11.

V50, DS50 and DT50 surge protective devices are approved as class I & class II SPD (or  T1+T2 SPD), designed for low-voltage power system lightning current & surge protection, used at the boundaries from lightning protection zone 0B -2 and higher.

With built in Prosurge’s high energy MOV, this range surge protectors ensure remarkable lightning current discharge capacity up to 7.5 kA 10/350μs and high reliability. The unique design of thermal protection provides quick thermal response and secure disconnection.
