PTC resettable fuses, also known as polyfuses, are electronic components designed to protect low voltage and current circuits from overcurrent and overvoltage. They provide a low-cost, solid state solution to the problem of “one time” protective fuses that are easy to install and use. PFRA.010.3 is a type of PTC resettable fuse frequently used in circuit protection applications. It is engineered to be used in a variety of industries, including automotive, medical, aerospace, military, and industrial.

PFRA.010.3 is an innovative PTC resettable fuse that offers excellent surge and overcurrent protection. The device is designed to trip and reset when exposed to a predetermined current level. The resettable fuse is capable of interrupting short circuit current up to 2000 Amps, and has a rated current of 0.3A.

Unlike standard fuse, the PFRA.010.3 does not require a physical fuse element to be replaced when it activates. It contains a resistive element – usually made of ceramic – that heats up when current passes through it. When too much current is flowing, the resistive element warms up and increases its resistance to the point where it trips open the circuit. When the device cools down, the resistance decreases and the circuit is reset. This eliminates the need to replace damaged fuses, which saves time and money.

The PFRA.010.3 is designed to be used in a variety of low voltage and current applications. These include computers, medical devices, vehicles, and various industrial equipment. The device is also engineered to provide overvoltage protection in AC and DC circuits. It is UL and CE approved, meaning it can be used in safety-critical applications. It is also designed to operate in extreme temperatures, making it suitable for a wide range of environments.

The PFRA.010.3 is easy to install and use, and does not require any maintenance or adjustments. It is also exceptionally reliable, with a high tripping accuracy and a long service life. Additionally, it is small and lightweight, making it easy to install in tight spaces. This makes it an excellent choice for portable equipment and handheld devices, as well as other small form components.

Overall, the PFRA.010.3 is an impressive PTC resettable fuse that can provide superior protection in a variety of applications. It offers high levels of surge protection, and its small size makes it suitable for even the most cramped spaces. The device is also designed to be reliable and easy to use, making it an excellent choice for companies looking for a solid state solution to their circuit protection problems.
