RN1 type indoor high-voltage current limiting fuse, melting characteristics

The product is used in overload or short-circuit protection for elctric transformer. The current limiting means that the fuse will cut off the circuit before the short-circuit current reaches the peak value.

Fusing characteristics

Current which passes the fuse when being1.3 times of its specified electric current, Do not fusing for an hour; When the current through the fuse is 2 times of its specined electric current, fusing in an hour; Refer to its fusing feature curve in chart 1when select the fuse.

Mainly used to protect voltage transformers, power transformers, and high-voltage distribution lines, suitable for various indoor high-voltage switchgear, ring main unit and other cabinets. Specific information is as follows: XGN2-10 indoor high-voltage fixed switchgear, GG-1A (F) indoor high-voltage fixed switchgear, HXGN15-12 indoor high-voltage ring main unit, KYN28A-12 indoor high-voltage movable switchgear, etc
