Lower Limit Calibration Of Drop-out Fuses
Date: | Read: 1
For rural power lines with short-circuit currents below 6kA, the RW7-10/6kA type drop out fuse should be selected. This not only meets the protection requirements of the line in the event of a fault, but also effectively avoids the risk of melting tube bursting due to insufficient arc extinguishing capacity, thereby improving the safety and reliability of rural power grid operation.
