PTC Resettable Fuses, or PTC fuses, are a type of electrical fuse used to protect electrical components from high inrush currents or short circuits. PTC fuses are designed to be reset once they have triggered to prevent any further damage to the protected component. The RKEF375K is a type of PTC fuse that is commonly used in a variety of applications.

RKEF375K fuses are typically used in low voltage (up to 600V) electrical systems, such as those in automotive and home appliances. They can be used to protect circuit components such as motors, relays, contactors, or other high power consumption devices. RKEF375K fuses are also reliable for over-temperature protection, making them popular in cooking appliances or water heaters, as well as in motor controllers and solar cell panel applications.

The RKEF375K is composed of a metal strip that acts as a fuse element. This element has a special coating on it that helps to protect the fuse from overcurrent surges. The coating is designed to detect when the current increases above an unsafe level, and when it does, it triggers the fuse element to open up a circuit. The components connected to the fuse are thereby protected from further damage.

The working principle of the RKEF375K is relatively simple. When the element is triggered by an over-current surge, it creates an open circuit. This stops the flow of electricity, allowing the components connected to it to cool down. Once the temperature has returned to a safe level, the element can be reset by simply pressing down and re-attaching the reset button on the fuse.

The RKEF375K provides an effective solution to over-current protection and is simple to use. Its reliable design ensures that it is well-suited for a variety of applications. From motor controllers to solar cells, the RKEF375K can help protect electrical components from damage due to sudden surges or short circuits.
