93.Types of fuses & material of HRC

October 02, 2018 Posted by AK No comments

There are 3 types of fuses.

1.Re-wireable type - This has one advantage, cheapness. Dis advantages include it often deteriorates due to oxidation and it may deteriorates under faulty conditions and damage surrounding property. 

2.Cartridge fuse - The rating is accurately known and the element is less likely to deteriorates, however it is not suited for high rated fault currents.

3.High Rupture Capacity (HRC) fuse - They will blow in approx. 0.25 to 3 cycles, this reduces danger to personnel and also reduces electro magnetic stress which tend to distort the apparatus.


1.Connectors and Caps - Made of copper or brass, attached by welding or soldering. Current ratings and reference number are stamped on the caps.

2.Body - High grade Ceramics

3.Filler - A quartz filler

4.Fuse element - Pure silver strip element

5.Quartz
