Wire Harness Manufacturers for Automotive Fuse Boxes
Selection of automobile fuses and fuse boxes
In the electrical circuit, the main function of the car fuse is to protect the wire. If there is current through, it will reach its fusing temperature within a period of time and interrupt the circuit.
The time for a fuse to blow is related to its own temperature rise. It depends on the ratio of rated current/rated power (I/IF):
The larger the value, the faster the fuse will blow.
The characteristics of the fuse are composed of two curves, and there are related standards (DIN, ISO, JASO)
For 30A current, this fuse will blow in 0.15s to 5s.
For 90A current, this fuse will blow in 0.02s to 0.10s.
According to the speed of fusing time, it can be divided into fast-blow fuse and slow-blow fuse.

Let's take an example to illustrate how this curve is represented:
For 30A current, this fuse will blow in 0.15s to 5s.
For 90A current, this fuse will blow in 0.02s to 0.10s.
According to the speed of fusing time, it can be divided into fast-blow fuse and slow-blow fuse.
