Application for LED lamps as the 2. and 3. level of overvoltage protection (T2 middle and T3 fine) in a 3-level of surge protection concept,
It decreases overvoltage and limits the overvoltage energy wave caused by inductance and switching procedures in the supply network,
Installation into the cable channels, installation boxes, or terminals of the protected appliance,
Protection against the transverse and longitudinal overvoltage (L/N, L/PE, N/PE),
The protection effect is provided by a varistor (MOV) combined with spark gap,
Optical or acoustical signalization of operational state.
