BR-25VG 3+1 25KA TYPE 1 SPD POWER SURGE PROTECTION DEVICE

The surge arrestors BR-25VG meet the Class I and Class II requirement class according to IEC 61643-11.
Powerful components, suitable for all kinds of common power systems.
Visual status display.
The unit is designed to be used between Zone O and Zone 1 (according to IEC62305-4 definition of Lightning Protection Area).
Available with optional remote signaling.
Simple standard rail mounting.
The use of high-performance varistors permits a rapid response time and a low protection level.
Application:
These devices protect low-voltage consumer systems from overvoltage.
It is applicable to lightning protection for the power system in areas with high lightning risk (LPZ0B or the interface between LPZ0B and LPZ1).
Applied in modular SPD Class I + Class II (Class B + C) for TT and TN-S power supply system.
