    20A-800A New Energy Electric Vehicle Fuse 50Ka 750V High Speed Fuses

    20A-800A 750V 50Ka High Speed New Energy Electric Vehicle Battery Fuse​

    This products are round tube bolted fuses, which have the characteristics ofsmall size, high breaking capacity, resistance to current impact, and canwithstand high-strength mechanical vibration and impact, wide temperaturerange impact, and strong chemicalload, and are suitable for the road vehicleindustry Application, can be used for short circuit and backup protection ofelectric vehicle drive power system, power conversion system, energystorage and power system, frequency conversion controller, charger, wireand other vehicle devices and equipment.

    Purpose and use

    This series of fuses are suitable for lines with rated DC voltage below 1000V, rated current of 100A-200A and breaking capacity of 20kA. They are widely used in chargers. Comprehensive protection of charging pile, on-board battery, on-board circuit system and inverter. At the same time, it has the characteristics of strong current limiting capacity, large breaking capacity and fast short-circuit breaking speed. It can withstand temperature shock, mechanical vibration shock, current shock, chemical load, etc. This series of products conform to ISO 8820, JASO D622 and GB / T31465 standards.

    Normal working conditions

    Normal operating conditions of ambient air temperature: - 5 ℃ ~ 40 ℃; allowable operating conditions: - 40 ℃ ~ + 125 ℃;Relative humidity: 5% ~ 95%;Atmospheric pressure: 61.6 kPa ~ 106.2 kPa.

    Structural characteristics

    The melting tube of the product is made of high-temperature resistant ceramic material, with high flame-retardant performance and strong hardness.

    The melt is sealed in the melting tube with a variable cross-section melt made of 99.99% pure silver. The melting tube is filled with chemically treated high-purity quartz sand and specially treated chemical materials as arc extinguishing medium. The contact surface is silver plated to ensure reliable electrical performance, greatly reducing temperature rise and power consumption; Both ends of the melt are firmly connected with the contact by spot welding, which greatly enhances the safety and reliability of breaking short circuit fault current
