Product Introduction

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.

Features
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.

Application
It required to be noted: product name and model No., voltage of fuse link, current of fuse link and quantity. The base or fuse link can be ordered separately. For example, 1. Fuse link RT18-32 380V/16A 1000 pcs, base RT18-32 1000 pcs, which can be also written as: RT18-32 380V/16A 1000 sets. 2. Fuse link RT18-63 380V/50A 8000 pcs, base RT18-63 600 pcs 3. Base RT18-32X 1000pcs (implies with indication lamp)

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.
