Sieno high quality SPD NDU5-200 Surge Protector Device

In parallel module type surge protective device has large lightning current discharge capacity, large circulation, each line max. discharge current could reach lmax= 160KAI8/20 s), suits for 220V/380V power supply distribution lightning protection.

This spd is module design, nice sealing performance, matched remote signal interface and faulty indicator window, installed in 35mm DIN rail, easy to wire. There has temperature control technology, over current fuse and thermal circuit breaker,automatic trip when degraded. Different specification satisfy, easy to maintain, could supply different working voltage level and lightning discharge current, also could customized according to different requirement.
