Type series FGHD 31.. Steel-grid fixed resistors1,0 - 12 kW with 2 terminals, for integration into switch cabinet Steel-grid fixed resistor, degree of protection IP 20 in fixed condition, in zinc plated steel sheet enclosure with 2 feed-through terminals for the resistor, that are integrated into the side-panel end plates, protected against contact according to BGV A2. Optional also with temperature switch (TS). ® if mounted on an appropriate surface © optional, type designation would be FGHD.U 31.. These overload factors are valid for a total cycle time of maximum 120 s You will find further details in chapter Technical Details pages T613E to T620E. An important application is the use as braking resistor for motor/generator drive of motors with frequency converters, where middle power ratings are to be integrated into a switch cabinet in a space saving way. Warning The user has to make sure that large dissipations are removed. We recommend an adequate forced ventilation. Example of dimensioning and selection of a specific unit: One phase braking resistor for frequency converter drive with temperature switch, short time dissipation 24 kW at 15% DCF, total cycle time shorter than 120 s, intermediate voltage circuit 650V; resistance value 18 Q; calculating of continuous dissipation: 24 kW : 4,0 = 6,0 kW; chosen: FGHDQ 3111204 - 18 FGHDQ 311 12 04 - 18 -no. of terminals(2) + 2 terminals for TS -number of steel-grids -type series T626E r04 FRIZLEN GMBH U.
