Applications

  • H.V HRC current-limiting fuses type XRNP for transformer protection is mainly used in AC 50Hz, rated voltage 3.6-40.5kV, rated current up to 6.3A circuit for protection transformers from overload and shirt-circuit.
  • It conforms to IEC282-1, BS and GB15166.2.

Design Features

  • XRNP type H.V HRC current-limiting fuses is insert installation. It is convenient for install and removal. The fuse link made of high-resistance metal wire and low-resistance metal wire. They are sealed in the fuse tube filled with chemically treated high-purity quartz sand. The fuse tube is made from heat resistance, high duty ceramic or epoxy glass. When fault circuit happens, the fuse link melts causing arc, quartz sand extinguish the arc immediately, signaling the melting or automatically cutting the circuit.
