PFRA.160.3

PTC Resettable Fuses are a type of fuse that is used to protect electronic components from overheating, short-circuiting, and over-current. The most common type of PTC Resettable Fuses are the PFRA, which is short for PolyFuse Reversible Action. The PFRA.160.3 is a popular model of this type of fuse, and it is designed for use in circuits with 12V to 40V DC applications. This fuse is designed to be used in medium-power applications, such as home appliances, automotive electronics, and LED lighting. In this article, we will explore the application field and working principle of the PFRA.160.3.

The PFRA.160.3 has a wide range of applications, such as automotive electronics, home appliances, LED lighting, and motor control systems. This particular fuse is designed to provide reliable protection to low power circuits in those areas. Its wide range of applications makes it ideal for a variety of applications. In addition, the PFRA.160.3 provides high-temperature stability, as well as short-circuit and over-voltage protection. This makes it an excellent choice for protecting electronic components from overheating, short-circuiting, and over-current.

The working principle of the PFRA.160.3 is based on the hysteretic effect. This effect occurs when a material goes through a reversible transition between two states when its temperature fluctuates. In the case of the PFRA.160.3, the temperature goes up when a load is applied and the transition occurs when the temperature passes a set temperature threshold. When this happens, the fuse will open and the current will be interrupted. This allows for a gradual reset of the device, without the need for manual intervention.

The PFRA.160.3 has several features that make it an ideal choice for medium-power applications. It has a fast response time, so it will be able to provide protection rapidly when necessary. Additionally, it has a wide operating temperature range, as well as a low temperature coefficient. This ensures that the fuse is able to remain stable under a wide range of temperatures, meaning it can be used in many different situations. Furthermore, the PFRA.160.3 has dual-contact safety switch, which allows for the reset of the fuse when it is tripped. This makes it easy to use and offers an extra layer of protection in case of an emergency.

In conclusion, the PFRA.160.3 is a versatile and reliable fuse that is designed for use in medium-power applications. It has a wide range of applications, as well as features such as a fast response time and a wide operating temperature range. It also has a hysteretic effect working principle, which allows for a gradual reset of the fuse. This makes the PFRA.160.3 an excellent choice for protecting electronic components from short-circuiting and over-currents.
