PSM 20

PSM-20 is the range of devices for discharging induced transient overvoltages (Type 2+3 / Class II+III), in accordance with IEC 61643-11. DIN rail plug-in format.

  • Suitable for the second stage of protection in supply distribution panels in which Type 1 protection devices are installed, or for the first stage of protection in residential, commercial or other applications not exposed to direct strikes and with no external lightning protection system.
  • High discharge capacity with an 8/20 μs waveform. Imax: 20 kA.
  • Exclusive devices for TNS, TNC, TT. 120/208 V, 230/400 V, 277/480 V networks.
  • Exclusive devices which are compatible with Power Line Communication (PLC) networks.
  • Remote and visual indication of life status of the protection device.
  • Reversible chassis to allow cable entry from above or below. Mechanically polarized cartridges depending on the network voltage, to avoid possible cartridge replacement errors.
  • Biconnect - two types of terminal: for rigid or flexible cable and for fork type comb busbar.
