PTC resettable fuses are a type of current limiting device specially designed to protect against short circuit faults. They are created when two or more independent devices are connected in series by a fusible element. When the current reaches a predetermined level, the PTC resettable fuse will auto-activate, interrupting the current and protecting the connected equipment.

PFRT.012.250.U is a specific model of PTC resettable fuse, suitable for applications ranging from 5 V up to 30 V DC. It is available in UL rating: 250 V UL 94V-0. It features a shrinking tube with an internal PTC element and an external pin that acts as the fuse element.

The working principle of PFRT.012.250.U is relatively simple. When the current crosses the preset threshold value, the PTC element inside the shrinking tube increases its resistance, which results in a decrease of current and an eventual interruption of the current flow.

PFRT.012.250.U can be used in various kinds of applications where protection against short circuit faults is of the utmost importance. It can be used in the medical industry, consumer electronics, automotive electronics, instrumentation systems, radio frequency identification (RFID) related products, and a range of industrial uses.

Its protective capabilities makes PFRT.012.250.U ideal for industries where reliable and safe operation are essential. PFRT.012.250.U is available in a variety of formats, allowing for convenient installation and simple maintenance. It is temperature-resistant and overvoltage sensitive, ensuring that it will not be damaged by overvoltage and will automatically reset once the current has dropped below the designated level.

PFRT.012.250.U is perfectly designed to protect both extremely sensitive, high-voltage components and more robust components that may be subject to intense loads. Its simple, yet effective design ensures that it can provide reliable protection from a number of unexpected power surges and load-related conditions as well, without metal fusing or repairing. It also features a rapid thermal response time, providing a safe and secure protection no matter the situation.

Given its versatile application field and working principle, PFRT.012.250.U is an ideal solution for any application where short circuit protection must be ensured. It is robust, safe, and efficient, making it the perfect choice for a broad range of industries and applications.
