170N3428 application field and working principle

Fuses are electrical protective accessories used in electrical circuits for circuit protection. One of the most popular fuse series is 170N3428 manufactured by Mingtai Electric Co., Ltd. It consists of a wide range of fuse products and ranges from low voltage to high voltage, UL, CCC, and IEC compliant, and can be widely used in UPS, communication power supplies, computer power supplies, automotive electronics, industrial control, and other products. Here, we\'ll mainly discuss the application fields and working principles of this series.

Application Field

170N3428 series fuse has wide application fields. It is suitable for over-voltage and over-current protection for power distribution systems, computer power supplies and communication power supplies, UPS equipment, battery-powered power supplies, household appliances, electrical equipment, automotive electronics, industrial control, and other products, and can work in any electrical environment.Moreover, the temperature range and wide dynamic resistance range of the 170N3428 series makes it suitable for harsh and severe environment.

Working Principle

The 170N3428 series fuse is based on the principles of thermal melting and short-circuiting. Under normal circumstances, it has a simple structure, so its conduction state is relatively stable. It is a current-limiting element, and its main purpose is to prevent high currents from damaging electrical or electronic components.When the current is too high and exceeds the current-limiting fuse’s rated current, the fuse wire melts and generates heat, separating the current-carrying circuit and protecting the components. The installation location must be correct and the rated current must be appropriate so that it can effectively protect the components.
