Multi-pole lightning current arrester for protection of low-voltage consumer's installations in business and residential areas against surges caused by lightning or switching actions in the network. The arresters can be installed at the transition 0A to 1 according to the lightning protection zones concept. Multi-pole lightning current arrester (class I) for single phase TN systems.
  • Remote signalling contact: break contact
  • Lightning current arresters type 1 (class I)
  • Test standard: IEC 61643-11 / EN 61643-11
  • No leakage currents, thus, allowing installation upstream of power meters
  • Operates independently of atmospheric air pressure and ambient humidity
  • Serial wiring with multi-functional terminals
  • Mounting on 35 mm DIN rail (EN 60715)
  • Degree of protection according to IEC EN 60529: IP 20
  • EAC certification
