4.Storage temperature:
EV Fuse Products storage temperature: -40°C ~ 105°C. The relative humidity is not more than 70% when 40°C. The relative humidity is not more than 80% when 30°C. The relative humidity is not more than 90% below 20°C.
Packaging storage temperature: -40°C ~ 70°C. The relative humidity is not more than 40% when 40°C. The relative humidity is not more than 50% when 30°C. The relative humidity is not more than 90% below 20°C, no condensation.
Fuses can be stored for average 1 year when the relative humidity ≦75%.
Not in the open air, fuses can be stored at most 30 days when the relative humidity 95%.
5.Mechanical features
5.1 copper cap
The copper cap should be firmly riveted to ensure that the copper cap cannot be removed when the fuse link is not damaged. After the sample is immersed in water at 15℃-35℃ for 24 hours and taken out, on each end cap, evenly apply a pulling force to 5N, keep it for 1 minute, the copper cap should not fall off.
5.2 Tensile test
One end copper cap fixing the fuse, then on the other end of the copper cap, apply a tension of 100N along the horizontal axis, The copper caps at both ends should not be loose and the pipe body should not be broken.
5.3 Tube strength test
After fixing the copper caps at both ends, apply a pressure of 200N to the center of the ceramic tube, the tube should not be broken.
