Purpose and Use
This product is a cylindrical bolt-connected fuse. It features compact size, high breaking capacity and excellent resistance to current surge. It can withstand high-intensity mechanical vibration and impact, wide temperature cycle shock, and severe chemical load. It is suitable for road vehicle applications, and provides short-circuit and backup protection for electric vehicle drive power systems, power conversion systems, energy storage and power systems, frequency conversion controllers, chargers, cables, andother automotive components and equipment.
Note: All test data in this specification are measured under DC conditions. Time constant requirements: for prospective test current ≥ 20 kA, adopt 10-15 ms; for prospective test current <20 kA, adopt 0.5 ~ 3 ms. The wiring method complies with ISO 8820 and GB/T 31465.
