Indoor Fuse H. V. Current-Limiting Rn Type

Product Description

High voltage indoor fuse for Voltage Mutual Inductor Protection: 

RN1 type indoor H. V. Current-limiting fuse is used for protectiong from overload and short circuit for power circuit. THe so-called current-limiting is the function of fuse cutting off the short circuit current before it reaching the peak value.

Fusing characteristics: 

1. When the passing current for fuse is 1.3 times of its rated current, it does not melt in 1 hour. 

2. When the passing current for fuse is 2 times of its rated current, it melts in 1 hour. 

3. Fusing characteristic curve of fuse see the following Fig, for reference of selecting fuse.
