Cartridge fuse RDF16

bladeHRClow-voltage

RDF16 sériés powder filled cartridge knife type contact fuse is suitable for the industrial electric distribution device of AC 50Hz, rated voltage up to 500/690V, rated current up to 1250A, as the use of the over-load and short-circuit protection for the circuit. Confirms to: GB13539.1-2008/IEC60269-1:2006; GB/T13539.2-2008/IEC 60269-2:2006 ► Normal operating condition and installation condition 3.1 - Ambient temperature: -5°C~+40°C, average value within 24h does not exceed +35”C, and the average value within one year should be less than this value. 3.2 - Altitude of installation place does not exceed 2000m 3.3 - Atmosphère condition The air is clean, and its relative humidity does not exceed 50% when the ambient temperature is at 40 °C. It is allowed relatively high humidity at the relatively low temperature, for example, the relative humidity can reach 90% when 20”C, and it should take considération of the condensation produced on the surface of product that is due to the temperature variation. 3.4 - Voltage When the rated voltage is 500V, the maximum value of system voltage does not exceed 110% of fuse's rated voltage; When the rated voltage is 690V, the maximum value of system does not exceed 105% of fuse's rated voltage. Note: the fuse link is fusing in a significantly lower than the rated voltage, the fuse indicator or fuse impactor may not act. 3.5 - Installation category: III 3.6 - Grade of pollution: not less than 3 3.7 - Installation position This sériés of fuse can be vertically, horizontally or obliquely installed at those opération occasions of without obvious shake, impact vibration.
