Fuse Selection Guide Of The LED Indicating Automotive Fast Acting Maxi Auto Blade Fuses

Although care is taken to properly design electrical and electronic circuits; overcurrents in the form of short-circuits and overload can occur. The sole purpose of fuses and circuit breakers is to protect personnel and/or equipment from serious harm when an overcurrent condition arises. This guide is intended to help create a better understanding the various parameters of overcurrent protection and the proper application of circuit protective devices. This guide creates a basic understanding of overcurrent principles and applications but is not intended to supplant sound engineering principles or replace specific application testing.

In order to select the proper protective device, the following parameters and criteria need to be considered:

1. What is the normal operating current of the circuit?
2. What is the operating voltage?
3. Is the circuit AC or DC?
4. What is the operating ambient temperature?
5. What is the available short-circuit current?
6. What is the maximum allowable I²t?
7. Are there in-rush currents available?
8. Is the protective device being used for short-circuit protection, over-load protection, or both?
9. What are the physical size limitations?
10. Is the PCB surface mount or thru-hole?
11. Does the fuse need to be "field-replaceable"?
12. Is resettability an issue?
13. What safety agency approvals are needed?
14. How will I mount the device?
15. What are the cost considerations?

What is the normal operating current of the circuit ?

In order to select the right amperage of the fuse, you first need to know the full-load steady-state current of the circuit at an ambient temperature of 25º C (68º F). Once the current value is determined, then a fuse rating should be selected as to be 135% of this value (taken to the next standard value).

For example, if the normal steady-state current is calculated to be 10 amps, then a 15A fuse rating should be selected [10 amps x 135% = 13.5 amps, the next larger standard size is 15A].

It is important to note that if the fuse is intended to be used in an environment with possibly very high or low ambient temperatures, then the nominal fuse current would need to be sized significantly higher or lower (see ambient temperature below).

What is the operating voltage?

The basic rule of thumb is that the voltage rating of the fuse must always higher than the voltage rating of the circuit that it is protecting.

For example, if the circuit voltage is 24 volts, then the fuse voltage rating must be higher than 24 volts (yes...it can be 250 V...just so long as it"s higher than the circuit voltage).
