Endurable, sustains multiple strikes.

LED status indication.

BR-50GR 1P+N is suitable for TT and TN-S system.

SPD indoor fixedly mounted, limiting voltage.

SPD has built-in disconnector, when SPD is invalid due to overheating or breakdown, the disconnector can automatically separate SPD from the network, meanwhile send an indication signal. If to be separated from network, the visible window will show red color.

Application:

Being total current arresters between the neutral and protective conductor in TT systems, the single-pole N-PE lightning current arresters of type BR-50GR NPE help to ensure fulfilling the requirements for protection of personnel and equipment in "1+1" circuits.

The BR-50GR NPE coordinated NPE lightning current arresters hold a special position among total current arresters. Due to their low voltage protection level, they can be directly coordinated with N-PE surge arresters of the BR-50GR surge arresters without additional decoupling coil.
