Steel-grid fixed resistor, degree of protection IP 00, with side plates for integration into a switch cabinet. Connection directly at the resistor. © optional, the type designation would be FKE.U 31.. Electrical and mechanical data • especially compact construction form, dimensions depend on number of installed steel-grids. • small to middle power rating • continuous power rating up to 22 kW • integration into switch cabinet possible • temperature switch optional (TS), with fast-on connectors 6,3x0,8; type designation would be FKEQ 31... Each resistor can be delivered with 2 or more connection lugs. Depending on the current the lugs are equipped with M6 or M10 screws. The resistor is mounted in a cabinet by means of the two side plates. Mounting of several partial resistors (e.g. 3-phases) into one resistor unit is possible. They are separated by insulation rolls. You will find suggestions for the dimensioning of the resistor for short time load in chapter “Technical Details”, pages T613E to T620E. For customer wiring you should use a heat resistant wire. Application Customized solutions like integrating a resistor unit into a switch cabinet, when a very compact construction form is needed. This table represents only a selection of our program. All numbers of steel-grids between 2 pc. (1,0 kW) und 44 pc. (22 kW) corresponding to our types are available. Type code and selection of units see Technical Details pages T613E to T620E. The dimensions A and B increase by 20 mm per each steel-grid element (SG) Example of dimensioning and selection of a specific unit: Three phase load resistor: for 3 x 3,0 kW = 9,0 kW for 3 x 230/400 V; 50 Hz, 3 x 13 A, 3 x 17,8 Q, (Rcold=16,9) starpoint on connection lug: selected: 3 S26 - 2,7 Q + 4 S25 - 2,2 Q = 16,9 Q; 3 x 7 SG type FKE 3122104 - 3 x 17,7 with typical power 3 x 3,0 kW, connection on 4 connection lugs at the resistor (value Rwanted) FKE 312 21 04 - 3 x 17,8 Thus various kinds of solutions are possible for many applications such as: • load resistors • charging or discharging resistors • braking resistors • starting and regulating resistors etc. • damping resistors 1-ohmic value + 10% -number of connection lugs -number of steel-grids -type series FRIZLEN GMBH U.
