Plug-in format

HS25-D10 is the range of devices for discharging induced transient overvoltages(Type 3 / Class III), in accordance with EN/IEC 61643-11. DIN rail plug-in format.
Ability to discharge induced voltage surges (8/20 μs). For very fine protection of sensitive equipment(1.2/50 μs). Installation downstream of type 2 protection.
■Suitable as the final stage of protection in panels with Type 2 protection devices installed upstream. The residual voltage left downstream is less than for Type 1 or 2.
They should be installed as close as possible to the equipment being protected.
■Discharge capacity with an 8/20 μs waveform. Imax: 10 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 flexible cable and for fork type comb busbar.
■Available with optional remote signalling.
