Steel-grid fixed resistors Type series FGF.. 31.. Pi Steel-grid fixed resistor unit, degree of protection IP 20 if mounted on an appropriate surface, with zinc plated steel enclosure. It is equipped with max. 2 terminals of different kinds mounted in or at the enclosure or in the attached terminal box. Some types can be provided with a temperature switch or with an integrated thermal overload relay or DC/POWERSWITCH. For your selection of a specific type you will find tables on the next page. ® if mounted on an appropriate surface ® optional (not for FGFG and FGFX), type designation would be FGF..U 31.. Technologies • low priced type, very compact design • continuous power rating up to 22 kW • for mounting on top of a switch cabinet (all types besides FGFD..) • for integration into a switch cabinet with terminals that are protected against contact (type FGFD..) • units may be wall or plate mounted, perforated steel sheet at the front, top and bottom, terminals at the bottom. • terminal type and size selectable according to mounting place and connection technics • optional with temperature switch (type FGF.Q) • optional with thermal overload relay (type FGFT) • optional in intrinsically safe version with FRIZLEN DC-POWERSWITCH® (type FGFX) Application These units are fitting especially for mounting on, beside or in a switch cabinet by their relatively flat and compact construction in 6 widths with various connections and monitoring possibilities (Please mind the description of the types). An important application is the use as braking resistor for motor/generator drive of motors with frequency converters, where high power rating is combined with low budget solution. You will find suggestions for the dimensioning of the resistor for short time load at chapter Technical Details, pages T613E to T620E. Warning When resistor is integrated into a cabinet we recommend to provide a corresponding forced ventilation by the user for better removal of larger dissipations. Details of the different types Type FGFG: Version with 2 flat type terminals up to max. 35 A rated current in the attached terminal box with cable gland. An additional temperature switch is not possible. Type FGFK(Q): Version like FGFG, with a bigger attached terminal box with cable glands, the space is sufficient for 2 terminals up to M8 (max. 115 A rated current), and for 2 additional porcelain terminals for an optional temperature switch (FGFKQ). Type FGFL(Q): Version, where all terminals are mounted on the terminal strip inside the housing. Terminals up to M8 (max. 115 A rated current) are accessible after disassembling a part of the cover. If equipped with temperature switch, there are 2 additional porcelain terminals on the terminal strip (Type FGFLQ).No cable glands. Type FGFD(Q): Construction with feed-through terminals up to max. 65 A that are protected against contact and directly fixed on the side plate. It is a space-saving solution for integrating into a switch cabinet. If equipped with temperature switch there are 2 additional protected feed-through terminals (FGFDQ). Type FGFT: Version with integrated thermal overload relay in the attached terminal box with cable glands up to max. 80 A rated current. With integrated short-circuit and overload signalling. Connection directly at the overload relay. Type FGFX: Intrinsically safe version with integrated FRIZLEN DC-POWERSWITCH in the attached terminal box with cable glands, up to max. 40 A rated current. With integrated short-circuit and overload protection inclusive switching off the resistor and signalling. Connection directly at the FRIZLEN DC-POWERSWITCH®. ® DGBM Nr. 20 2009 015 851.9 Attention: Only for DC voltage up to 850 VDC.

Steel-grid fixed resistors Monitoring options of the type series FGF.. 31.. 1. Signalling -no disconnection! This warning has to be considered by the customer, e.g. by a warning or disconnection of the mains through the customer. Details, on page T615E. 1a) with temperature switch (FGF.Q) Different types can be equipped for temperature monitoring with a temperature switch which monitors an overloading of the resistor by a normally closed contact free of potential (NCC). Connections pis. look at picture 1a) 1b) with thermal overload relay (FGFT) An eventual overload of the resistor...
