PTC Resettable Fuses are a widely used line of products from company rectangles EIP formed from a company with a long history of research and development of passive electronic components. The PTGL10BB120N0P52A0 is one such product in their range, rated to handle up to 10A, for AC and DC applications.

The working principle of a PTC Resettable Fuse is based on the understanding of how two basic properties of a material change under different temperatures. If a material has a positive temperature coefficient (PTC) and process of self-healing, it can be used to create a self-resetting fuse. The PTC Resettable Fuse has two main parts: a resistive element and a semiconductor.

The resistive element is a conductive material with PTC properties. When a current passes through the conductive path, the element begins to heat up and causes its resistance to increase. This increase in resistance generates more heat, causing the temperature of the element to rise further. Once the trip temperature is reached the element breaks the circuit disconnecting it from the load.

The second part of the fuse is the semiconductor. It is used to restore the uninterrupted connection after the over-current event has occurred. When the current in the circuit is back to safe levels the semiconductor automatically reconnects the circuit. This process is repeated over and over until the over-current issue is permanently corrected.

The PTGL10BB120N0P52A0 brand of PTC Resettable Fuses are designed for a wide range of applications, ranging from consumer devices to industrial machinery. The most common areas of applications for these fuses include safety and protection of electronic devices, over-current prevention, surge protection and voltage regulation. It can protect sensitive circuits by disconnecting them from power supply when the nominal current is exceeded.

This particular fuse also offers protection from over-voltage and reverse voltage by limiting its current and self-disconnecting from the circuit when the voltage exceeds that rated level. Furthermore, it is also capable of providing relatively fast response time in overload conditions making it suitable for devices operating at high frequencies.

In summary, the PTGL10BB120N0P52A0 is a high quality, rugged and reliable resettable fuse used for safety and protection in a number of applications. Its two main components – the resistive element and the semiconductor – work together to form a resilient circuit with a highly efficient self-resetting fuse, capable of protecting sensitive equipment from damage due to over-current, over-voltage and reverse voltage.
