HS2VV5-D20 is the range of devices for discharging induced transient overvoltages (Type 2+3 / Class II+III), in accordance with EN/IEC 61643-11. DIN rail plug-in format.
Ability to discharge induced voltage surges(8/20 μs), while offering very fifine protection of sensitive equipment(1.2/50 μs).
■Suitable for the second stage of protection in supply distribution panels in which
Type 1 protection devices are installed, or for the fifirst stage of protection in residential, commercial or other applications not exposed to direct strikes and with no external lightning protection system.
■Discharge capacity with an 8/20 μs waveform. Imax: 20 kA.
■Exclusive devices for TNS, TNC, TT , IT earthing systems.
■Exclusive devices which are compatible with Power Line Communication networks.
■Biconnect - two types of terminal: for rigid or flflexible cable and for fork type comb busbar.
■Available with optional remote signalling.
