OBV5-C40 is a range of devices designed for discharging induced transient overvoltages (Type 2 / Class 11), in compliance with EN/IEC 61643-11 standards. These devices come in a DIN rail plug-in format and are capable of discharging induced voltage surges (8/20 µs).

  • They are suitable for use as the second stage of protection in supply distribution panels where Type 1 protection devices are already installed. Alternatively, they can be used as the first stage of protection in residential, commercial, or other applications not exposed to direct lightning strikes and lacking an external lightning protection system.
  • These devices provide a discharge capacity with an 8/20 µs waveform, with a maximum discharge current (I max) of 40 kA.
  • They are exclusive devices for TNC earthing systems.
  • In addition, these devices are compatible with Power Line Communication networks.
  • They feature a biconnect design, offering two types of terminals for both rigid and flexible cables, as well as fork-type comb busbars.
  • An optional remote signaling feature is available.
