PTC Resettable Fuses are current-limiting devices designed to protect against electrical overcurrent events. The RGEF1000-2 is an example of such a device and is used in a variety of systems, from domestic to industrial. It is a type of poly-switched fuse, which are activated by an electric field, and designed to reset once the overcurrent has been eliminated.

The RGEF1000-2 consists of a ceramic body with a conductive layer, a steel insert, and a polymer sealant. The body is filled with a dielectric material which increases the breakdown resistance of the fuse, allowing the device to operate in harsher environments. The conductive layer acts as a bridge between the body and the steel insert. It serves to resist overcurrent, preventing excessive current flow.

The RGEF1000-2 is designed for use in a range of applications, from consumer electronics to power distribution. Its design allows for protection against electrical currents up to 50A. The device is used to protect against common overcurrent problems such as overloads, motor stalls, and momentary short circuits. It is also suitable for applications that require an emergency shut-off in the event of an electrical surge or fault.

The working principle of the RGEF1000-2 is fairly simple. When an overcurrent is detected, the fuse is activated, causing the conductive layer to open the circuit and prevent further current flow. Once the overcurrent event has been eliminated, the device will reset, allowing current to flow again. This resetting process is why PTC Resettable Fuses are superior to other overcurrent protection options, such as circuit breakers. Circuit breakers will trip and disconnect the circuit every time an overcurrent is detected, which is not only inconvenient but can be detrimental to a device’s overall performance.

The RGEF1000-2 is a versatile and reliable overcurrent protection solution, providing fast and effective protection in a variety of applications. Not only is it capable of protecting against common overcurrent faults, but it is also capable of resetting itself, eliminating the need for time-consuming reset processes. This feature makes the RGEF1000-2 an ideal choice for systems and applications that demand fast and effective protection such as consumer electronics, motors, and power supplies.
