Product Description
In parallel module type surge protective device was designed accordingly to IEC standard, each line max. Discharge current
Imax could reach 20-40kA, suits for 220/380V power supply distribution system lightning protection.
This SPD is module design, nice sealing performance, and has remote signal interface, faulty indicator; 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.Technical ParametersModel
