PTC (Positive Temperature Coefficient) Resettable Fuses are now widely used in many industrial and consumer electronic applications. The RHEF1300 is a standard PTC fuse that offers reliable protection from excess current and short circuits. The fuse can be automatically reset but requires manual reset if it reaches its maximum current setting. This article will discuss the application field and working principle of the RHEF1300.

Applications of PTC Resettable Fuses

The RHEF1300 has many application fields due to its adjustable current settings and resettable function. Examples of applications for the RHEF1300 include over-current protection in automotive, industrial, and consumer electronics, as well as various telecommunications and networking applications. The RHEF1300 can also be used to protect against over-voltage and overloads in a variety of devices and applications.

Among the common applications of PTC resettable fuses are the protection of charging systems for laptop computers, hand-held electronic devices, and various types of battery packs. The RHEF1300 is also an excellent choice for protecting sensitive electronic devices from potential damage caused by electrical surges. Other applications for the RHEF1300 include lightning protection, surge protection, dead-short protection, and secondary current protection.

Working Principle of RHEF1300 PTC Fuse

The RHEF1300 is a type of PTC resettable fuse that utilizes a polymeric positive temperature coefficient (PPTC) device. This fuse is designed to monitor and regulate current in circuits. The PPTC device has a low resistance at temperatures below its activation point, allowing current to flow freely through the circuit.

When the operating temperature of the device rises to the activation point, the resistance increases sharply, creating a short circuit and preventing the current from flowing. This is the resettable function of the RHEF1300. The device will automatically reset itself after the operating temperature is reduced, allowing the current to resume to its normal level.

The RHEF1300 has a wide range of current settings and the selection is based on the specific application requirements. The current values for this device are typically listed in a range between 0.28 A to 400 A. The current rating of the fuse is determined by the size of the PPTC element used, as well as the temperature ratings.

Safety Features of the RHEF1300

The safety features of the RHEF1300 are designed to protect both the device and the equipment being protected. The resettable function allows for quick and easy recovery from an overload or short-circuit condition. Additionally, the RHEF1300 utilizes an arc suppression feature to reduce the risk of sparks or other hazards that may be caused by an electrical malfunction.

The RHEF1300 also incorporates a containment feature that prevents dangerous high temperatures from damaging the device or any nearby electronics. This containment feature works by limiting the temperature of the PPTC device, and limiting the current it can handle in any given time interval.

Conclusion

The RHEF1300 PTC Resettable Fuse is an invaluable tool that offers reliable protection for a variety of applications. The adjustable current ratings make it easy to select the appropriate fuse for a particular application. The safety features of the device help to ensure optimal performance and safety for any setup.
