Excess-voltage suppressor OPN-280 ZOI (LVA 280B-FL)

Descriere

OPN excess-voltage suppressor of IEK brand are intended for protecting electric networks and equipment at direct or indirect influence of lightning and surge overvoltages. Suppressors are designed for exploitation in AC electric networks under 1 kW (50 Hz). Connecting OPN-XXX ZOI suppressors to SSIC is carried out with the help of ZOI clamp, to non-insulated lines – with the help of ZSGP clamps. Connecting OPN-XXX Sh is performed onto bus taps of phase and neutral conductors. The product range contains a clip to be attached to the SIP wires and the tire bends of conductors.
