The charging pile functions like a tanker in a gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, depending on the voltage level. Charge all types of electric vehicles. The input of the charging post is directly connected to the AC grid. The output has AC and DC points, and both are equipped with charging plugs to charge the electric car.

The design of the charging post must be considered safe and reliable, so overcurrent and overvoltage protection must be used on the input, output and communication interfaces with safe and reliable protection devices. Here we recommend a large voltage high current fuse SPFJ160 from Littelfuse, the leader in the fuse industry. This model is an ideal circuit protection solution for the DC output of the charging post and has been widely used in the field of charging posts.

The SPFJ series is the first fuse in the electrical industry to be listed in the UL 2579 certification catalog to protect 1000VDC, 70-450A large voltage and high current devices. It is designed and manufactured to meet the requirements of IEC Standard 60269-6 and has passed the VDE 125-450A application certification. These rigorous standards ensure equipment and personnel safety, making the SPFJ series truly a global product. The 125-450A specification offers a J-shell size that saves equipment manufacturers a lot of space and significantly reduces costs. At the same time, the company's Littelfuse can also provide 1000VDC fuse holders for this series to meet the unique application needs of some customers.

The SPFJ160 is rated at 1000VDC/600VAC and has a rated current of 160A to meet the requirements of DC charging piles of all grades. The rated breaking current is up to 200KA@600VAC or 20KA@1000VDC. The higher rated breaking current means that the fuse is less prone to burst under extreme conditions, so it is safer and more reliable.
