0208010.DRT1P

Fuse is one of the most common electric components. It is mainly used to protect electric circuits and electrical appliances. In this article, we will take 0208010.DRT1P fuse as an example to introduce the application field and working principle.

Application Field

The 0208010.DRT1P fuse is suitable for a variety of application fields, such as consumer electronics, ICT, automotive, security and etc. This fuse can work under environment of -55°C~125°C and is perfect for circuits with direct current or alternating current. It has features such as being miniaturized, integrated, and being able to breaking the circuit under affect of over-current. This type of fuse is widely used in two-wire and three-wire home appliances and auto starte systems.

Working Principle

In simple terms, the working principle of 0208010.DRT1P fuse can be divided into three steps. First, it detects the over-current. When the current exceeds a certain value, the fusible alloy inside the fuse will melt and cut off the current flow. Secondly, when there is an over-voltage, electronics inside the fuse will blow up and cut off the circuit. Lastly, when there is excessive heat, the fuse can cut off the circuit due to its built-in over-temperature limits.

The 0208010.DRT1P fuse works according to the principle of thermal inertial relay. When the current passes through a certain limit value, the contact temperature of the fuse rises, and the fusible alloy melts, causing the contact to move away violently and breaking the circuit. However, due to the low heat resistance of the fusible alloy, the contact will be rapidly returned, re-closing the circuit. This is the reason why the fuse has a slow blow and even a no blow characteristics.

The 0208010.DRT1P fuse is characterized by its miniaturization, which can reduce the space occupied by the fuse. Its integration has made it more stable in operation, and its breaking ability under the action of over-current, over-voltage and over-temperature has greatly improved the safety of electric circuits and electrical appliances. These features has helped 0208010.DRT1P become the fuse of choice in many application fields.
