Medium-voltage disconnect switch FTr 12

3-poleverticalhorizontal

The 1- and 3-pole Outdoor Disconnectors FTr areapplicable for a rated voltage range of 12 kV to38,5 kV and a rated current range from 400 A to4000 A. The rated short time current upto 50 kA for aduration of 3s depending on the type has beentested.The 3-pole Earthing Devices FES are useable for arated voltage range of 12 kV to 38,5 kV.A rated short time current up to 63 kA is dependingon type specified.All switches are type-tested according to EN 62271-102 and are suitable either for vertical mounting (900operating angle) or horizontal mounting (1100 opera-ting angle).For each switch an instruction manual for trans-portation, mounting and commissioning is inclu-ded. This instruction manual should be strictlyfollowed.The disconnectors and earthing devices are able tocarry its rated short time and rated withstand currentaccording to the data as the type Plate. The base fra-mes of the switches are hot-dip galvanized. The maincontact system is made of electrolytic copper and thesurface is silver plated acc. to QTL 0200.Rustproof pressure springs maintain the requiredcontact force over the whole mechanical life.
