Description:
1.The fuse operates normally within the temperature range of -5°C to 40°C, and no additional correction is required.
2.The allowable usage conditions are -40°C to 85°C.
3.Within the range of allowable usage conditions, refer to this table.
1-The metal end cap and purple copper legs are riveted and re-welded to ensure they will not fall off due to vibration.
2-The fuse tube is made of high-alumina ceramic, which withstands electric arc impact and does not deform under high temperatures.
3-The fuse element is precision-stamped from imported Japanese alloy materials, ensuring durability against current shock.
4-The arc extinguishing medium is high-purity quartz sand, which is selectively cleaned and processed.
5-A curing process developed by WESTKING is used to fix the quartz sand, preventing the fuse element from being pulled apart by vibrations and effectively reducing the intensity of electric arc impact.
6-An interference fit is used for the inner and outer end caps to reduce resistance.
