1kV High-Current Current-Limiting Fuse (1600A–3150A)

The 1kV series heavy-duty current-limiting fuse is designed for AC 50/60Hz low-voltage power distribution systems with a rated voltage of 1kV. It provides stable, high-performance overcurrent and short-circuit protection in a wide rated current range from 1600A up to 3150A, making it widely used in industrial power supply, large equipment, power rectification systems, and heavy-load distribution scenarios.With excellent current-limiting performance, high breaking capacity and stable time-current characteristics, this fuse effectively protects large transformers, high-power motors, rectifier devices, capacitor banks, generator sets and other critical electrical equipment from damage caused by fault currents. It features low power loss, low temperature rise and strong impact resistance, ensuring long-term safe and stable operation in harsh industrial environments.
