Tubular fixed resistors Type series FZ / FU Type series FZB / FUB 12 – 1000 W for integration 12 – 300 W with threaded rod IP Cemented (FZ) and uncemented (FU) wirewound tubular fixed resistor, degree of protection IP00. Type series F.B additionally with mounted threaded rod, fixing vertically to mounting surface. Variable connections at the soldering, fast-on or screw clips* on the resistor. FZ 100x24ST (with fast-on adjustable clip) *Particular specifications for „low ohmic values“ – for details please look on the following page Type designation (standard) Types with soldering connections (4,8x0,5) connection directly at the resistor optional, depending on construction size with screw, fast-on or soldering connection adjustable clips (Ags.) available (please mind the hints on this page and on the following one) with type series F.B.. only small mounting space is needed mounting in switch cabinets You will find indications for the relationship between load capacity and temperature on the surface as well as for the dimensioning of the resistor at short term load in chapter “Technical Details”, pages T103E-T108E. Application As ballast, limiting, filter or series resistors etc. for integration into devices and customised units. Our type series F.B.. is very well applicable in switch cabinets. We fix the threaded rod for you in a space-saving way. Efficient use in your manufacturing systems. Special design various tube sizes as well as lower and higher ohmic values on request beginning with size D=24 also with temperature switch (TS) with fast-on connections 6,3 x 0,8 soldering connections, pretinned Types with fast-on connections (6,3x0,8, also solderable) size D=24 D=35 D=45 We provide M3 screw connections for construction sizes with diameters D=16 and M4 with D=24/35/45 M5 with D=65. Also fast-on connections (6,3x0,8) are available for sizes with D=24/35/45. For sizes with D=16 the soldering connections can also be used as fast-on connections (4,8x0,5). You will find the electrical and mechanical data on the next page. Types with screw connections (M3 / M4 / M5) size D=16 up to D=65 Hints for the versions with adjustable clips For the cemented fixed resistors with adjustable clip we decrease the available maximum ohmic value. Since otherwise while adjusting the clip, the danger of breaking the wire would be too large because of too thin wires. The adjustable clip may only be adjusted in a condition free of voltage and after sufficient loosening and cooling. All the adjustable clips of our fixed resistors in tubular version are equipped with silver contacts. When selecting please consider that the maximum surface temperature (ST) should not exceed 300°C. Please consider as well that the resistance value may be reduced with versions where several adjustable clips are combined, especially in the lower range of ohmic values and with short tube lengths. In that case we have to select a higher total ohmic value. Example of dimensioning and selection of a specific unit: Adjustable power resistor for mounting into a switch cabinet with 2 additional taps: continuous dissipation 150 W; resistance value 100 ; rating 110 V DC, mounting by threaded rod on mounting plate, adjustable resistance taps by 2 adjustable clips, connection at fast-on clips, Selected: FZB 200 x 35 S2T – 100 with continuous dissipation 150 W Alternatively: FZB 160 x 45 S2T – 100 (continuous dissipation also 150W) FZB 200x35 100 ohmic value 10% with fast-on clips and 2 fast-on adjustable clips according to list type series (FZ.. is standard)
