Our fuse link is not just a component, but a critical investment in the safety and reliability of your energy storage systems. It combines advanced protection features with robust construction, ensuring your systems remain operational and efficient under all conditions.
Our energy storage fuses have earned the trust of industry leaders across various sectors. Here are some reviews from GRL’s satisfied customers:
1. Working humidity range: At a maximum temperature of 40℃, the relative humidity does not exceed 50%. At a maximum temperature of 20℃, the relative humidity should not exceed 90%.
2. Normal operating temperature range: -5℃ to 40℃. Permissible temperature range: -40℃ to 80℃.
3. Altitude: no more than 2000m. When the altitude exceeds this value:
1) The temperature rise of the fuse increases by about 0.5k for every 100 meters above sea level.
2) For every 100 meters of elevation increase, the ambient temperature decreases by about 0.5 ℃ on average.
3) Under normal circumstances, fuses used in open environments can ignore the effect of altitude on rated current and still be selected following standard conditions.
4) For fuses used in closed environments, if the ambient air temperature of the box or the temperature inside the box does not decrease significantly with the elevation, it can still reach more than 40℃, it is necessary to reduce the rated current capacity.
