FUSE TYPE
There are four basic types of fuses:
(1)Slow Blow/Time lag fuses
(2)Dual element slow blow fuses
(3)Fast acting fuses
(4)Very fast acting fuses
Slow-blow fuses are ideal for circuits with a transient surge or power-on inrush.These circuits
include:motors,transformers,incandescent lamps and capacitate loads.Fast-acting fuses response quickly and are used in circuits without transient inrush currents. Very fast-acting fuses often have silver linked. Because the fuses need to have ability to limit the current,these fuses are usually used to protect semiconductor circuits.
