Short description:

Provides surge protection for IT systems and devices in the voltage range up to 60 V (except custom solutions, e.g., telephone systems with ringing voltage).

Overvoltage protection is also possible for DIN-35 rail-mount terminal blocks. Multi-stage surge arresters in rail-mount terminal blocks (792-80x Series) of just 6 mm width ensure cost-effective protection for control and bus technology (e.g., LON® network, PROFIBUS network, binary signals).


  • Protect your system against overvoltage
  • Slim, space-saving design
  • Control operational costs by preventing expensive, unplanned downtime
  • High operational reliability and system uptime


The coordination characteristics of the surge arrester provide information about its discharge capacity and protection capability.
