RN Series
RN Series High-voltage AC Fuses  
This series of high-voltage AC fuses can be used in indoor power system of 50Hz AC, rated voltage from 3KV to 35KV to protect power circuit, transformer, voltage transformer and other electrical equipment from overloading and short-circuit. It also can be used to protect the branch circuit of the power system. Before the short current of the circuit reaches the maximum, the fuse will cut off the circuit.
