PowerPro BCD TNC…TNS…TT

Combined devices PowerPro BCD provide protection against both direct lightning currents, and of the induced surges. Limiters of this series are intended for installation in low-voltage power supply systems for industrial, commercial and residential areas. In small structures, the offered device may be a single overvoltage protection, in particular in GSM rooms, in container spaces and in individual houses.

Designed for installation in zones 0A-2, in accordance with the concept of protecting zones (IEC 61312).

  • fast installation, compact modular design;
  • patented sealed gas discharge tube;
  • no blow hole - it is not required to keep the permissible distance to other devices;
  • lightning current limit up to 100 kA (10/350 ms);
  • follow current limitation;
  • very high insulation resistance Riso > 10 GOhm;
  • voltage limit <0.75 kV to 1.0 kV;
  • V-shaped connection is possible;
  • no leakage currents - can be installed in front of the counter;
  • optional contact of remote signaling system (FM version);
  • maximum reliability;
  • parameters independent from pressure and humidity;
  • great overvoltage withstand.
