PTC (positive temperature coefficient) Resettable Fuses are widely used in a variety of industries, from aerospace to consumer electronics. In the automotive sector, for example, these fuses are used to protect circuits against over-current and over-voltage conditions. AGRF1100-2 is one of the most popular PTC Resettable Fuses and is used in high-current applications such as air conditioning systems, automotive batteries, heating systems, and other automotive electric components.

AGRF1100-2 is a small size, glass encapsulated PTC Resettbale Fuse with two independent terminals for easy installation. It has a current interrupt rating of 20 Amps at 25°C and is designed to protect high amperage circuits. Its maximum operating temperature is 125°C and its maximum Voltage is 250VAC/VDC. It also features an end of line resistance of 4Kohm, which helps maintain an adequate level of protection for the circuit.

The working principle behind the AGRF1100-2 is quite simple. When the circuit is subjected to an abnormal current flow, the temperature of the fuse element rises. When the temperature reaches the point of its resistance, it triggers a self-resetting process and breaks the circuit. The process can take as little as 25 milliseconds, and the fuse is able to reset itself multiple times, once the abnormal current is removed. This helps protect expensive electrical components from sustained over-current and over-voltage conditions.

In addition to its self-resetting feature, the AGRF1100-2 also offers the advantage of being less prone to false triggering than other types of fuses. This is due to its small size and low power requirements, which allow for faster response time and more accurate triggering. As a result, the AGRF1100-2 can be used to protect higher amperage applications than other types of fuses.

In summary, the AGRF1100-2 is a reliable and cost-effective solution for protecting against abnormal current flows. Its self-resetting feature ensures faster response time and more accurate triggering, while its small size and low power requirements make it suitable for a wide variety of applications. Furthermore, its end of line resistance provides the needed protection against over-current and over-voltage conditions.
