PTC Resettable Fuses, also known as Polymer Positive Temperature Coefficient devices, are commonly used to provide circuit protection. The RXE030 is one of these fuses and is used in a wide variety of applications. This article will examine the RXE030\'s application field and working principle in detail.

The RXE030 is mainly used as an over-current protection device in applications where a particular limit must not be exceeded. This fuse functions by allowing a current to pass through until it surpasses what the device is set to, at which point the fuse will will trip and shut off the power. This process is reversible; once the power is remove the device will reset and function as normal again.

RXE030\'s have a wide range of applications. From consumer electronics and medical equipment to industrial and automotive applications, these devices provide a fast and reliable means for preventing damage from over-current situations. They are also commonly used to protect wiring from damage due to temperature increases.

To understand the working principle behind the RXE030, it helps to know a few basic principles of physics. PTC devices work by using the principle of thermistors, which are materials that show resistance to temperature changes. As the temperature of the device increases, its resistance decreases, and when the device exceeds a certain temperature it creates a voltage differential that turns off the power supply. This device is configured to turn off at a precise temperature, ensuring that it is not damaged by the temperature increase.

The RXE030 also works on the principle of Positive Temperature Coefficient, or PTC. When current flows through this device it generates heat, which then increases the temperature of the device. As the temperature rises, the internal resistance of the device increases, and when it reaching the threshold it will trip and shut off the circuit, protecting it from damage.

In addition to the thermal protection provided by the PTC device, the RXE030 also features AC and DC disconnects. This allows the device to react to both voltage and current increases, ensuring that an over-current situation does not cause any damage to the circuit or the device.

The RXE030 is a versatile device that can be used in a wide variety of applications. It is capable of providing reliable over-current protection as well as thermal protection, allowing it to be used in a range of environments. With its combination of features, the RXE030 is one of the most popular resettable fuses on the market.
