Introduction to Fuses

Fuses are a common type of safety device which interrupts an electric circuit if it becomes overloaded. Fuses protect people from exposure to electrical shocks and prevent fire damage due to short circuits or other overcurrent conditions. Fuses are used in a variety of consumer and industrial electronics applications, such as power supplies, computers, automotive systems, and electrical equipment.

3403.0172.11 Fuse: Application Field and Working Principles

The 3403.0172.11 Fuse is a small 2-pole mini-fuse rated at 32 V DC and 15 A for overload and short circuit protection. It is widely used to protect circuits on vehicle electrical systems, such as in the instrument panel, door locks, antilock brake systems, and airbag systems. The 3403.0172.11 fuse is also used in a variety of industrial and consumer electronic applications such as computers, audio/video equipment, motorized appliances, and power supplies.The 3403.0172.11 fuse is a miniature blade-style fuse, featuring blade terminals which push into the female receptacle, and a plastic insulation housing. This style of fuse is very common in automotive and industrial electronics and provides excellent protection for electric circuits.The working principle of the 3403.0172.11 fuse is based on the electrical current rating. When the electrical current exceeds its rated capacity, the membrane inside the fuse melts and causes an open circuit which disrupts the flow of electricity. This prevents further damage due to overheating or short circuit conditions.

Conclusion

The 3403.0172.11 Fuse is a small 2-pole mini-fuse rated at 32 V DC and 15 A for overload and short circuit protection. It is widely used to protect circuits on vehicle electrical systems, as well as in a variety of industrial and consumer electronic applications. The 3403.0172.11 fuse features blade terminals and a plastic insulation housing and works on the principle of electrical current rating. When the electrical current exceeds its rated capacity, the membrane inside the fuse melts and causes an open circuit which disrupts the flow of electricity, preventing further damage due to overheating or short circuit conditions.
