PTC Resettable Fuses, also known as Polymeric Positive Temperature Coefficient (PPTC) fuses, have become an increasingly popular safety device. This is due to their ability to provide reliable over-current protection in a wide range of electrical and electronic systems and applications. The RUEF600-2 is one such example of this product. In this article, we’ll discuss the application field and working principle of the RUEF600-2, and it’s importance in electrical and electronic systems.

The RUEF600-2 PTC Resettable Fuse is designed for use in electrical and electronic systems. This product provides reliable over-current protection for other components in the system. It has an excellent tracking accuracy and can detect a wide range of over-current conditions, including over-voltage, short circuits, and inrush currents. Additionally, the fuse can be used in both AC and DC applications.

When it comes to the working principle of the RUEF600-2, this particular PTC Resettable Fuse works by detecting an over-current situation and then selectively blocking the current. This blocking action prevents further current from flowing in the circuit, in order to protect other components in the system. The current limiting action of the fuse is accomplished by the use of a specialized semiconductor material known as a Positive Temperature Coefficient (PTC). This material has a very high resistance when heated, and it becomes even higher as the temperature increases.

When the current exceeds the maximum allowable limit, the resistance of the PTC material increases drastically, and the current is blocked. This action trips the fuse, protecting the components in the circuit from damaging over-current conditions. When the current is cut off, the Resistive Temperature Detectors (RTD) on the fuse detect a drop in temperature and will reset the fuse automatically.

The RUEF600-2 is a valuable safety device for a wide range of electrical and electronic systems. It provides reliable over-current protection, and its selective current block action prevents damaging over-current conditions from damaging other components in the system. Additionally, its temperature detecting ability allows it to automatically reset itself when the current is cut off.
