PTC (positive temperature coefficient) resettable fuses offer a number of advantages over traditional fuses. They are able to provide reliable overcurrent protection as well as automatic resetting of the circuit breaker each time an overcurrent trips. The wide range of applications for a PTC resettable fuse includes overcurrent protection and current limiting in applications such as automotive, industrial, explosion proof, and many more.

RGEF800 is a standard ptc resettable fuse featuring a simple design with good performance. It has a rated operating voltages of AC 85 - 250V and a rated current of 8A.The RGEF800 is designed to be triggered when current exceeds a certain threshold set by the user, at which point it creates a self-clearing break in the circuit that prevents dangerous overloads and reduces the threat of catastrophic arcing.

The working principle of RGEF800 is based on the fact that it contains a special material inside that can withstand high temperatures without breaking down or causing damage. When the current flowing through the circuit reaches the set trigger level, it causes the material inside the protective device to heat up and reach its melting point. This melting point is a predetermined temperature, above which the material inside the fuse will break down. As the material breaks down, a spark is created and a gap is created in the circuit, breaking the flow of current.

Once the thermal fuse has been triggered, the current must reset it and the device must be replaced. The resetting of the thermal fuse is achieved by cooling the material inside until it reaches a lower critical temperature. At this point, the material will reform and no longer will cause an interruption in the circuit.

The RGEF800 ptc resettable fuse is used in a wide variety of applications to protect electrical circuits from overcurrents. It is ideal for applications where the current levels may fluctuate quickly or where the circuit design does not allow the use of a standard fuse. The thermal fuse can be designed to trip at an exact current level and provide simple, effective protection.

The wide range of RGEF800 applications includes but is not limited to automotive, industrial, explosion proof, and many more. It is used to protect circuits that are prone to temporary surge, such as electric motors and compressors, and can provide effective circuit protection in situations where conventional fuses are not suitable. In addition, the thermal fuse can be used in DC circuits, where the current is usually constant, to provide additional protection in the form of current limiting.

The RGEF800 thermal fuse is available in a variety of sizes and ratings, allowing it to be used in a wide range of applications. Different reset levels can be set depending on the type of application, allowing the fuse to be tailored to suit the needs of the specific circuit. This makes it the go-to choice for many applications where reliable overcurrent protection is needed.
