Energy Saving


2/8

IS 13703 / IEC 60269 New Standard for HRC fuses superceding IS 9224

HN & HF Fuse-Links conform to the new standard and will offer the following advantages :Low watt lossNon deterioration of fuse-linksProper protection to cablesComplete discrimination

New standard means more advantage for you

High breaking capacity : 100 kA for HN Type and 80 kA for HF Type

Fuse blown indication : Through a red pop-up indicator. Low let through energy

Low watt loss : Lower Power Loss in our fuses, gives you

Saving of powerCooler running of associated products like SDFs conform to

IS 13703 (Part 2) / IEC 60269-2

Features and benefits

L&T, India's largest manufacturer of low tension switchgear,offers the new generation of low watt loss HRC fuse-links typeHN & HF designed as per the new IS 13703 / IEC 60269 standards.

Guidelines for selection

While selecting fuse-links, the following points should be considered :

Fuse-links type HF & HN are suitable for system voltage up to 415 V

Select the suitable size and rating of fuse-link for switch-disconnector fuse unit as per the fuse selection chart

Ensure that the breaking capacity of the fuse link is higher than the prospective fault current

Fuses should be selected such that discrimination is achieved with other protective devices in the system

Rated voltage : 415 V Rated breaking capacity : 100 kA at 415 V
