Three Phase 40KA Low Voltage Surge Protection Device SPD for Electrical Network Protection

BR-40 series surge protective devices are suitable for C grade surge protection, protecting electrical networks from thunder shock. These devices are typically installed in low voltage main distribution boxes at the incoming end of buildings.

BR-40 Series surge protective devices (SPD) are suitable for AC 50/60Hz, TT, TN-C, TN-S, TN-C-S and other power supply systems, providing protection against indirect and direct lightning effects or other transient over voltage conditions.

Installed at distribution board (DB) within a building. The first gate to prevent lightning strike from entering your house via electricity supply line. The Type 2 SPD is the main protection system for all low voltage electrical installations. Installed in each electrical switchboard, it prevents the spread of overvoltage in the electrical installations and protects the loads. Type 2 SPD is characterized by an 8/20 µs current wave.
