General:
XRNT-12 high voltage fuse is used in indoor alternative current 50Hz, rated voltage 10kV system, and it can be matched with other protection apparatus (such as: load switch, vacuum contactor), for protection components on power transformer and other electric apparatus for overload or short circuit protection elements.
Main Technical Data:
1. Fuse can reliably break any fault current between minimum breaking current (2.5-3) times rated current of flux, and 31.5kA rated breaking current, under specified working conditions.
2. Time-current characteristics curve (Fig.1), upper part of minimum breading current is broken line.
3. Limit current characteristic curve (Fig.2)
4. I2t characteristic curve (Fig.3)
