Cylindrical fuse RT18

cartridgeClass gGcapacitor

RT18/HG30 series filling closed tubular type cylindrical cap fuse is suitable for the industrial electric distribution device of AC 50Hz, rated voltage 380V, rated current up to 63A, as the use of circuit's over-load and short-circuit protection. Confirms to standards: GB13539.1-2008/IEC60269-1:2006; GB/T13539.2-2008/ IEC60269-2:2006 Normal operating condition and installation condition 3.1 Ambient temperature: -5C~+40C, average value within 24h does not exceed +35C, 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 Atmosphere condition 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 20C, and it should take consideration of the condensation produced on the surface of product that is due to the temperature variation. 3.4 Voltage The maximum value of system voltage does not exceed 110% of fuse's rated voltage. 3.5 Installation category: III 3.6 Grade of pollution: not less than 3 3.7 Installation position This series of fuse can be vertically, horizontally or obliquely installed at those operation occasions of without obvious shake, impact vibration. Note: if the fuse is used in the different from the normal installation specified condition, it should be negotiated with the manufacturer. Scope of breaking and usage category Breaking scope of this series fuse link is "g", the usage category is "G", which is the general use full scope of breaking capacity fuse link.
