BDM-024-V/1-FR1-CIB

Lightning current arrester with two-stage switch protection of personal data for the bus CIB.

  • installation at the entrance to the building near the protected equipment, at the interface of zones LPZ 0 – LPZ 1 and higher

  • ​​​​​​​can also be used to protect the interfaces of control systems MaR, EZS, EPS, etc.

  • against longitudinal overvoltage (line - protective earth) rough protection and against transverse overvoltage (core - core, GND) rough and fine overvoltage protection

 

  • removable module, coupling impedance (R - resistance), line separated from protective earth by lightning arrester
