Product Description


The H-type and J-type fuses are respectively optimized for different application scenarios. The H-type fuse, with its compact design and small size, is highly suitable for small-sized electric vehicles with limited space. The J-type fuse, however, is larger in size and has a higher current carrying capacity, making it more suitable for large-sized electric vehicles and electric vehicles.


The EV14H750 is a new energy vehicle protection fuse produced by WESTKING, designed for voltage platforms below 750VDC. It is mainly used for the protection of branch circuits and has a maximum current range of 60A. This fuse features a small size and high breaking capacity, making it an excellent choice for electric vehicle

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.


Let us introduce you to the WESTKING EVFUSE, the structure of a safe and reliable EV fuse should be like this

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.
