CSH

CSH is the most robust range of single pole Type 1/Class I lightning current arresters, able to discharge energy (current) from a direct lightning strike (10/350) on an external lightning protection system (LPS) or overhead supplies, in accordance with IEC 61643-11. DIN rail monobloc format.

  • Suitable as a first step of protection in incoming power supply panels and in areas of high atmospheric exposure.
  • Discharges impulse currents with a 10/350 μs waveform: 25-50 kA per phase.
  • Follow current quenching capacity. Ifi: 50 kA.
  • Single pole devices for TNS, TNC, TT and isolated IT earthing systems.
  • Leakage current free (LCF).
  • Multidischarge technology.
