PTC Resettable Fuses have many various kinds of applications ranging from home appliances, consumer electronics, and aviation to automotive industry. The MF-RX135-2-99 an example of a PTC resettable fuse.

These fuses work by employing the principle of positive temperature coefficient (PTC). The PTC principle works by heating the fuse filament when an electrical current runs through it. The filament tripping point is dependent on the specific design of the fuse, and the melting point is what determines the current rating. Thus when the fuse is exposed to a current higher than its rating, the filament melts, releasing a small amount of gas debris which impedes the current. This is known as tripping. However, as the current fades, the debris cools, reforming the filament, thus allowing for normal operation of the device. This type of fuse is re-usable and is often referred to as a "self-healing PTC fuse".

MF-RX135-2-99 PTC resettable fuses are currently used in several applications across multiple industries. These include but are not limited to high-performance surge protection, current-limiting in power supplies, over-current protection of motors, batteries and other power sources, over-voltage protection in low-voltage power supplies and over-load protection in lighting fixtures. It can also be used as an external protection device, protecting electronic components from over-loading.

In addition to its use as an over-load protection device, the MF-RX135-2-99 is also used for safety in the event of shock or fire. Its structure and materials offer many advantages over traditional fuses, such as low contact resistance and fast response. Its fast response time also helps to prevent equipment from burning out while providing a high degree of reliability. It is also designed to operate in temperatures up to 105°C and is rated to break currents up to 135A.

The main working principles behind the MF-RX135-2-99 are current sense, power adjustment, and self-trip. The current sense feature senses when a harmful level of current passes through its components and automatically trips to protect equipment or components from being damaged. The power adjustment feature allows users to select the desired breaking capacity within the fuse rating limits. Lastly, the self-trip feature allows the fuse to trip upon heat buildup or an increase in current, safeguarding the device from further damage.

Overall, the MF-RX135-2-99 is a versatile PTC resettable fuse that offers a variety of applications. It is suitable for a variety of home appliances, consumer electronics, automotive, and aviation applications. It is highly reliable and robust and its superior performance, fast response, and low contact resistance make it a reliable partner in protecting devices against over-current, over-voltage, and short circuit.
