3kV High-Current Current-Limiting Fuse (4150A)

The 3kV 4150A high-current fuse is a heavy-duty current-limiting protection component designed for AC 50/60Hz medium-voltage power systems with a rated voltage of 3kV. With an extra-large rated current of 4150A, it provides stable, powerful overcurrent and short-circuit protection for ultra-high-power industrial equipment and large-capacity power distribution systems.Featuring excellent current-limiting performance, high breaking capacity and stable temperature rise control, this fuse effectively safeguards large rectifiers, electric arc furnaces, electrolysis equipment, power converters, busbar systems and other critical high-power devices against damage from fault currents. It is specially designed for continuous heavy-duty operation in harsh industrial environments.
