PTC Resettable Fuses are an important component in many applications, particularly where a certain degree of safety must be maintained. Among the most commonly used PTC Resettable Fuses, PTR060V0250-BK is a popular one due to its high reliability. This article focuses on the application field and working principle of PTR060V0250-BK.

Application Field of PTR060V0250-BK

The application field of PTR060V0250-BK includes various industries, such as automotive, aircraft, naval, heavy machinery, electrical equipment, and medical equipment. It is suitable for applications where a certain degree of safety is required to protect electrical components. And it can also be used for applications where high power and high current are simultaneously needed.

In addition, PTR060V0250-BK has a wide range of operating temperatures. It can operate between -40°C to 80°C and withstand a continuous operating temperature of 125°C. This makes it suitable for applications exposed to high temperatures.

Working Principle of PTR060V0250-BK

PTR060V0250-BK is a resettable fuse, also known as a polyfuse, consisting of a heat-sensitive polymer composite material. It has two metal strips that act as terminals, each connected to one of the ends of the material. When the power passes through the material, it generates heat, and when the temperature reaches a certain point, the material melts and breaks the connection between the two terminals, eliminating the power. This is known as tripping.

When the temperature drops below the tripping point, the material resets itself and reestablishes the connection between the two terminals. This type of fuse is self-resetting and requires no external resetting as required with other types of fuses. As such, it is very reliable and is considered to be an ideal safety device in a variety of applications.

Conclusion

PTR060V0250-BK is a popular PTC Resettable Fuse due to its high reliability and wide range of applications. It operates between -40°C to 80°C, has excellent heat-resistant properties, and is self-resetting, making it suitable for applications where a certain degree of safety is required. Its working principle is based on heat-sensitive material – when the temperature rises above a certain point, the material melts, breaking the connection between the two terminals, and when the temperature drops below the tripping point, the material resets itself and reestablishes the connection.
