PTC Resettable Fuses are a form of ceramic fuse that has been fast growing in popularity over the past decade. Ceramic fuses, also known as re-settable fuses or polymeric force temperature sensing fuses, are ideal for high-temperature applications where the temperature can be from 50-210°C (122-410°F). This type of fuse utilizes a Polymer Positive Temperature Coefficient (PPTC) disc which is self-heating resulting in a temperature increase. When the temperature increase reaches a specific level, the current is interrupted and the fuse is activated. The PPTC disc then cools down to the original temperature and the current is allowed to flow again.

MF-RX110/72-2 is a type of PTC resettable fuse. It is perfect for use in appliances, consumer electronics, power supplies and many other applications. The MF-RX110/72-2 is a compact and easy-to-install fuse which offers both over-current and over-temperature protection in one housing. It is rated to handle 110A at 72V and its overtemperature rating is a robust 180°C (356°F). Its time-delay action provides over-current protection with the response time of under 200ns.

The working principle of the MF-RX110/72-2 is relatively simple. When a circuit element reaches its over-temperature rating or an overload occurs, the red colored PRT element fitted on the fuse will heat up and expand, effectively opening the circuit and preventing further damage. The PRT will then cool down and return to its regular shape, allowing the current to flow normally. The PRT element can be reset and the fuse can be used multiple times, as long as the temperature doesn’t exceed its over-temperature rating.

The MF-RX110/72-2 is used in a variety of applications including industrial equipment, medical equipment, electric scooters, aviation electronics, rail designs, renewable energy systems, LED and lighting designs, gas-powered equipment and more. The fuse is widely used due to its excellent safety features, small size, and ease of installation. It is also extremely durable and reliable, making it an excellent choice for applications that operate in harsh environments or experience high electrical demand.

The MF-RX110/72-2 PTC resettable fuse is a great solution for applications that must withstand high temperatures, extremes of current, and severe environmental conditions. Its fast response time and ease of installation make it the ideal choice for applications that require a temperature and overload protection circuit solution. The fuse can be easily implemented in existing circuit designs, or can be used in new designs for added safety.
