Ambient temperature: -5℃~+40℃, the average value within 24h does not exceed +35℃, and the average value within one year should be less than this value. The altitude of the installation place does not exceed 2000m
Atmosphere condition: The air is clean, and its relative humidity does not exceed 50% when the ambient temperature is at 40℃. It is allowed relatively high humidity at a relatively low temperature, for example, the relative humidity can reach 90% when 20℃, and it should take into consideration the condensation produced on the surface of the product that is due to the temperature variation.
Voltage The maximum value of system voltage does not exceed 110% of the fuse's rated voltage.
Installation category: III
Grade of pollution: not less than 3
Installation position This series of fuse can be vertically, horizontally, or obliquely installed at those operation occasions without obvious shake, or impact vibration.
Note: if the fuse is used in a different from the normal installation specified condition, it should be negotiated with the manufacturer.

Structure characteristics This series of fuse is consisted of fuse link, fuse holder (fuse base, fusion loading component). Fuse link is consisted of fuse tube, melt and filler. The variable cross-section melt of pure copper belt or wire is sealing into the high strength fuse tube, there filled into the fuse tube with the high purity of quartz sand that is processed by chemical as the arcing medium. Two ends of the melt are spot welded to be firmly electric connected with the end plate (or connecting plate), which forms the cylindrical cap fuse. Fuse holder is consisted of the fuse base and fusion loading component, it appears full sealing type structure when the fuse operations. There can be with fusing indication lamp on the fusion loading component, the indication lamp will lighting when the fuse link is fusing to remind the operator. The holder is installed by the TH35 standard rail, easy and convenient. The wiring terminal of two ends are connected with the external wire by the screw.
