Fitur:
The surge arrestors BR-25M meet the Class I and Class II requirement class according to IEC 61643-11.
Labeled connections.
Electrical surge protector work by diverting the extra energy in the electrical surge away from the main circuit, usually to “earth”.
Surge protection devices (SPD) which is connected at the main distribution board is constantly monitoring the supply voltage.
Aplikasi:
These devices protect low-voltage consumer systems from overvoltage.
