High-voltage fuse XRNP1-10-12KV 0.5A 1A 2A 3 protection fuse tube core mutual inductance PT current-limiting fuse

High-voltage current-limiting fuses are suitable for AC 50Hz systems with rated voltages of 3.6 to 12kV. They can also be used in conjunction with other electrical equipment, such as switches and contactors, to provide overload or short-circuit protection for electric motors, transformers, capacitors, and other power equipment.

Current-limiting fuses are fuses that can safely interrupt all possible currents within their rated current and current-limiting range. They limit the melting time at the rated voltage to be equal to or less than the duration of the first main wave or symmetrical current wave, while also limiting the current to be less than the peak current.
