Selection Guide Of The Auto Fuse 40A 32V

 

The many factors involved in the fuse selection process are listed below:

1. Normal working current;

2. Application voltage (AC or DC);

3. Ambient temperature;

4. Overcurrent and the time the fuse must be blown;

5. Maximum fault current;

6. Pulse, impulse current, inrush current, starting current and circuit transient value;

7. Structural size constraints, such as length, diameter or height;

8. Necessary agency appraisal certificates, such as UL, CSA, VDE and other military departments;

9. Things to consider: easy replacement, axial lead, visual indication, etc.;

10. Fuse holder parts: fuse clip, mounting box, panel mount, P.C. board mount, RFI screen, etc.

Normal operating current: When operating at 25°C, the current rating of the fuse is usually reduced by 25% to avoid interference fusing. For example, a fuse with a current rating of 10A is generally not recommended to operate at currents greater than 7.5A at an ambient temperature of 25°C. For details, see "Rating Reduction" above and "Ambient Temperature" below.

Voltage: The voltage rating of the fuse must be equal to or greater than the effective circuit voltage. See "Voltage Ratings" for exceptions.

Ambient temperature: The current carrying capacity test of the fuse is carried out at an ambient temperature of 25°C, and this test is affected by changes in ambient temperature. The higher the ambient temperature, the higher the operating temperature of the fuse and the shorter its life. Conversely, operating at lower temperatures will extend the life of the fuse. The fuse also gets progressively hotter when the normal operating current reaches or exceeds the rated current of the selected fuse. Practical experience has shown that at room temperature, fuses should operate indefinitely if used within 75% of the listed fuse current ratings.

 

 

What does slow blow fuse mean? What does it do?


Slow-blow fuses are also called time-delay fuses. Their time-delay characteristics show that they remain intact when a non-fault pulse current occurs in the circuit and can provide protection for long-term overload. In some circuits, the current at the moment of switching is several times larger than the normal operating current. Although the peak value of this current is very high, it appears for a short time. We call it pulse current and also call it inrush current or surge current. Ordinary fuses cannot withstand this current. If an ordinary fuse is used in such a circuit, it may not be able to boot normally. If a larger fuse is used, it will not be protected when the circuit is overloaded. The melt of the time-delay fuse is specially processed. It has the function of absorbing energy. Adjusting the amount of energy absorption can make it not only resist the impact current but also provide protection against overload. The standard has provisions on the delay characteristics. If the standard's specified characteristics cannot meet your requirements, you can contact the manufacturer to solve it.
