Fast Acting Square Fuse NFS F5A 300V 8x4x7mm Black For Battery Charges

Fast Acting Square Fuse NFS F5A 300V 8*4*7mm Black For Battery Charges

Features Of The Square Fuse

* As we all know, fuses have the characteristics of small size. Compared with other fuse devices, the size of square fuses is also small among many fuses. In comparison, a lot of space has been reduced.
* Secondly, except for the two leads, the surface of the square fuse is made of plastic materials, so the surface is insulated, which has the effect of flame retardant and insulation.
* Finally, another advantage of the square fuse is the ability to segment. The breaking capacity of the open square fuse is 35A/250VC, which is slightly different from Littel's 392 miniature fuse, but because it is a domestic fuse, the cost performance is still very high. If it is not very demanding, choose our company square fuse is also very advantageous.

Advantages and disadvantages of fuses

1. Disadvantages of fuse:
In the past, electronic equipment and instruments used traditional fuses for overcurrent protection, but they could only protect once. If they were blown, they had to be replaced. In addition, abnormal fuses would also be blown, such as the moment of power-on, unplugging and inserting devices, poor contact, etc. Using the fuse for too long will cause the fuse to blow. When the fuse is replaced, it should be replaced with a fuse of the same specification. However, in the industrial field, it often happens that the fuse is replaced with whatever fuse exists, resulting in wrong replacement. Accidents in which components burn out and cause failures to expand frequently occur.

2. Advantages of self-recovery fuses:
The zero-power resistance of the resettable fuse at room temperature can be made very small, and the high-current products are only a few milliohms, the power consumption on the road is small, can be ignored, and the volume is relatively small. Self-recovery fuses can be connected in series in vulnerable circuits for overcurrent protection and thermal fuses, with fast resistance mutation speed, in the order of several ms, small heat capacity, short recovery time, impact resistance, and cyclic protection up to 8,000 times . The resettable fuse can be used as an over-temperature fuse, so it reflects the performance of the thermal fuse and the function of the thermal fuse to a certain extent in the circuit. To achieve the dual protection function of over-current protection and over-temperature protection in the circuit.
