Operating safely in a distribution network requires different switching points to obtain maximum service continuity in case of fault on the network. TPS can be used in various applications in the secondary distribution network. Construction Characteristics The switchboard is made of a metal structure composed of galvanized steel sheets that are assembled using rivets and bolts. This structure is built to withstand the electrodynamic stresses during the operation. A switch and earthing switch are fixed to this structure. A switch envelope made of epoxy resin makes the isolation possible between the structure and live parts. An operating mechanism, a mechanical position indicator and a voltage indicator are positioned in the front of the unit. The position of the switch is given by the mechanical indicator whereas the voltage signalling lamp indicates the presence of voltage. Visibility of main contacts can be checked through an inspection window positioned above the operating mechanism. In the front of the unit there is a door giving access to different compartments, e.g. cables, fuses and measurement. When the unit is equipped with a low voltage auxiliary compartment it is situated in its upper part. Flexibility Compact Safety Easy Operation Easy Installation Reduced Maintenance IAC A-FL 12,5kA 1s The series guarantees the internal arc protection on 3 sides up to 12,5kA for 1s. IAC A-FLR 16kA 1s The series guarantees the internal arc protection on 4 sides up to 16kA for 1 s. The robust and reinforced metal structure provides protection against internal arc. IAC A-FLR 21kA 1s The TPS is also available in a version that guarantees the internal arc protection on 4 sides up to 21kA for 1 s. The robust and reinforced metal structure provides protection against internal arc.
