Cartridge fuse RT19

power

RT19 Séries power filled cartridge eylindrieal cap fuse is suitable for the industrial electric distribution device of AC 50Hz, rated voltage 380V, rated current up to 125 A, as for the use of circuit's over-load and short-circuit protection. Confirms to standards: GB13539.1-2008/IEC60269-l: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 excccd 2000m 3.3 - Atmosphère condition The air is clean, and ils relative humidity does not exceed 50% when the ambient température is at 40 C. It is allowed relatively high humidity at the relatively low température, for examplc, the relative humidity can rcach 90% when 20 C, and it should take considération of the condensation produccd on the surface of product that is duc to the température variation. 3.4 - Voltage The maximum value of system voltage does not excccd 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 sériés of fuse can be vertically, horizontally or obliquely installed at those opération occasions of without obvious shakc, impact vibration. Note: if the fuse is used in the différent from the normal installation specificd condition, it should be negotiated with the manufacturer.
