PTC Resettable Fuses

PTC Resettable Fuses, or Polymeric Positive Temperature Coefficient Resettable Fuses, are electronic protective devices used to protect electrical systems, devices and components from overcurrent, short-circuit and over-temperature damages. These devices have different working principles based on their applications. The RGE600 series of PTC Resettable Fuses is a popular product, and along with its many advantages, also has a specific working principle and application field.

Application Field of RGE600 Series Resettable Fuses

RGE600 series PTC Resettable Fuses are primarily used to protect circuits from overcurrent and short-circuits. These protective devices are used in a wide variety of applications, including portable electronics, consumer products, communications equipment, and industrial and commercial machinery. With its power rating of 10 A, it can be used to protect low-voltage applications such as 12-volt DC systems and 24-volt DC systems. Additionally, the RGE600 series PTC Resettable Fuses is suitable for high-power applications like ITE (information technology corresponding equipment), UPS (uninterruptible power supply), and AC/DC adapters where high surge current protection is required.

Working Principle of RGE600 Series Resettable Fuses

RGE600 series PTC Resettable Fuses are unique in their working principle. Unlike traditional fuses, these devices can be reset after they\'ve opened, which makes them more reliable and cost-effective. The PTC Resettable Fuses are designed with a positive temperature coefficient material that switches to a low resistance when a current passes through it. When the current reaches the rated maximum value, the device will heat up and the material will switch to a zero resistance state and open the circuit. After the current is reset, the fuse will cool down and the material will switch back to its low resistance state, resetting the fuse and allowing current to flow through the circuit.

Advantages of Using RGE600 Series Resettable Fuses

There are several advantages to using RGE600 series PTC Resettable Fuses over traditional fuses. First, these fuses are designed to be resetable, which allows them to be used multiple times without having to replace the fuse. This makes them more cost effective than traditional fuses. Second, RGE600 series PTC Resettable Fuses can provide quicker response times and better protection from over-current and short-circuit damages. Additionally, these devices are highly reliable, even when exposed to extreme temperatures or shock and vibration. Finally, they offer an excellent thermal trip curve, which is the curve that shows the relationship between the current passing through the fuse and the temperature of the fuse.

Conclusion

The RGE600 series PTC Resettable Fuse is an effective and reliable tool for protecting circuits from over-current and short-circuits. It is primarily used in low-voltage and high-power applications where high surge current protection is required. Additionally, it offers several advantages over traditional fuses such as being resetable, faster response times, increased reliability and an excellent thermal trip curve. Therefore, the RGE600 series PTC Resettable Fuse is an excellent choice for all applications requiring protection from over-current and short-circuits.
