Working environment conditions:
1.1 Ambient temperature: -40℃~+125℃.
Refer to air temperature directly surrounding the fuse rather than room temperature. In many applications, the fuse has quite high temperature, because the fuse is used in supports or base of different structure, and the entire fuse is installed in a closed power distribution box or control cabinet;
1.2 Altitude: Not exceed 2,000 meters;
1.3 Atmospheric conditions: The air is clean, and its relative humidity does not exceed 50% at the maximum
temperature 60℃; a higher relative humidity is allowed at a low temperature. For example, the relative humidity can be up to 85% and the maximum relative humidity can be up to 90% at 20℃; the middle condensation may occur occasionally due to temperature changes under those conditions.
1.4 Pollution degree: 3.
1.5 Installation category: III.
1.6 Installation site: The fuse shall be installed in places where there is no obvious shaking or impact vibration;
1.7 If the working conditions are different from the above, please contact the manufacturer.
