OBV10-I-50 is the most robust range of Type 1/Class I lightning current arresters, capable of discharging energy (current) from a direct lightning strike (10/350) on an external lightning protection system (LPS) or overhead supplies, in accordance with EN/IEC 61643-11 standards. These devices come in a DIN rail monobloc format.

  • They are suitable as the initial line of protection in incoming power supply panels and in areas with a high level of atmospheric exposure.
  • These devices can discharge impulse currents with a 10/350 µs waveform at a rate of 50 kA per phase.
  • They are exclusive devices designed for TNC earthing systems.
  • These devices are compatible with Power Line Communication networks.
  • They feature a biconnect design, offering two types of terminals for both rigid or flexible cables and fork-type comb busbars.
