TNR-X/B+C Surge protective device
Application scope

B+C surge protector is mainly used for weather, transportation, post and telecommunications, office, electric power, housing, railway and so on. In the actual installation process, it often cannot meet the requirement, installation distance between both ends more than 5 meters, because of the installation space problem. In this case, the B+C type lightning arrester is recommended.

Main features

High quality components, modular design, and remote control alarm and dry contact are used to facilitate remote monitoring of the protector state, fast response time, large impact current, low residual pressure, easy installation and simple maintenance.
