The RN2 and RN4 series products are suitable for indoor distribution systems with AC 50Hz and rated voltage of (3-35) kV, as overload or short-circuit protection for voltage transformers.

Product Features

The RN4 series indoor high-voltage current limiting fuse consists of a base and a fuse tube. The melting tube consists of a ceramic shell and two end conductive copper caps. It is equipped with a ribbed ceramic tube wrapped with molten material, and the inner space is filled with quartz sand, which plays a role in extinguishing the arc.
