PTC Resettable Fuses, designed with over-current protection functionality, are widely used in many fields of industry. One of the common uses of PTC Resettable Fuses is in the protection of printed circuit boards. This type of fuse is ideal for providing reliable and cost effective over-current protection in both commercial and residential applications.

The MF-RHT400-AP application field is among the most common in the world of printed circuit board protection. It is a resettable PTC fuse with time-delay functionality providing protection against both thermal and inrush over-currents. This particular PTC Resettable Fuse has been designed to provide reliable over-current protection on up to 300A AC systems.

The working principle of this type of PTC Resettable Fuse is relatively simple. When a current greater than the pre-defined limit or an inrush current flows through the fuse, the PTC active element will activate and open the contact automatically. This allows the current to be safely dissipated to avoid any further damage to the surrounding environment and also maintains the protection of the system.

Upon activation, the PTC Resettable Fuse will effectively prevent further over-currents from flowing through the system. The thermal fuse will remain open until the temperature of the active element returns to its original state, which usually happens within a few seconds. Once the original temperature is reached, the PTC active element will reset itself and the protection is restored.

The main advantage of the MF-RHT400-AP application field is the high level of accuracy it offers as well as its reliable and cost effective operation. The robust construction of this PTC Resettable Fuse also ensures that it will perform optimally over time and will not create any instability in the surrounding environment. This PTC Resettable Fuse is an ideal choice for all medium and high-end printed circuit board applications.

In conclusion, the MF-RHT400-AP application field and the working principle of PTC Resettable Fuses make them an ideal choice for over-current protection in medium and high-end applications. This type of PTC Resettable Fuse offers reliable performance and cost effective operation, as well as providing a high level of safety and accuracy. Furthermore, with its robust construction and reliable operation, it can be used in a wide range of applications with minimal maintenance and excellent longevity.
