PTC Resettable Fuses is an effective and frequently used current protection device. AHRF200-2 is one of the most effective PTC Resettable Fuses in the market. It is mainly used to protect AC and DC circuits from overload or short circuit, providing long time and high current safety protection for power supply system.

The AHRF200-2 is a polymeric positive temperature coefficient (PPTC) rescuer fuse composed of conductive polymer and element metal with 20A rated energy rating. It is designed to protect AC circuits, low voltage DC supplies, as well as USB port and motors. This device has a small size of 11.9mm*5mm and a solid ability to bear impact. The maximum power dissipation is 40W at room temperature, making it suitable for most electrical components. All of these features provide impressive overcurrent/short circuit protection for electronic components.

The working principle of AHRF200-2 is to automatically cut off the flow of electric current when the temperature goes beyond the chosen temperature by PTC element. When electric current goes beyond the rated current level, the PTC element in the AHRF200-2 will be heated up quickly, resulting in a rapid increase in resistance. When the resistance reaches a certain value, the current will be cut off and the temperature of the PTC element will be maintained until the circuit cools down and the device is reset.

The AHRF200-2 can be used for a variety of applications. In the automotive sector, it is used in the vehicle dashboard\'s electronic parts, preventing them from overloading or being damaged by short circuit. It is also used in the protection of low voltage circuits in home appliances, consumer products, or telecom devices. It can be used to protect electronic circuits in medical devices, such as defibrillators, which need to be kept secure from overloads to avoid severe malfunctions or malfunctions.

In addition, it can be used for high temperature inductor protection, electric tool protection, and USB port. It can even protect lighting applications such as solar lamps, street lights, and landscape lighting, providing a safe solution for these applications’ circuits. The AHRF200-2 is also found in the motor protection and overload protection for automotive motors, compressors, generators, pumps, and other types of rotating machinery.

Apart from high temperature inductor, electric tool protection and USB port protection, AHRF200-2 is a reliable device to protect electric tools from overcurrent or short circuit with a temperature range between -40℃ to +85℃. In addition, it is an ideal choice to protect circuit against overcurrent or short circuit with a typical hold current of 208% from its rated current and a maximum current of 24A, making it a cost-effective device for a variety of applications.

The AHRF200-2 is a robust and reliable device that provides a safe and stable operation for different types of applications. It has impressive current resistance, characterized by a maximum current of 24A, and a temperature range of -40℃ to +85℃. Additionally, it has a small size of 11.9mm*5mm which makes it suitable for narrow spaces. All of these combined features make the AHRF200-2 a reliable and cost-efficient PTC Resettable Fuse dedicated to provide safe protection both to application and user.
