RHE070

PTC Resettable Fuses have become an increasingly popular choice for short circuit protection in many electronics applications due to their electrical characteristics and a variety of advantages they offer. RHE070 is one of the most common fuses for this purpose, offering a maximum hold current of 0.7 at 65℃ for a maximum of 10,000 cycles. This device is also an integrated temperature limit controller, allowing the circuit to be restarted when the temperature returns to normal.

Application Field: RHE070 is designed primarily for use in low voltage applications as single-phase internal house transformer protection. It is used on any type of equipment requiring built-in overcurrent protection, such as ON/OFF cooling fan motors, blowers, and machinery on other pieces of equipment.

Working Principle: The RHE070 is a resettable fuse, which means it will open the circuit when it detects an overload and reset itself once the overload is gone. When the device is overloaded, the heating element in the fuse melts and open the circuit. Once the overload is gone, the heating element and the circuit reset itself and the current can flow again. The resetting process requires the temperature to return to normal, meaning the device is temperature-sensitive.

The RHE070 is designed to open the circuit at 0.7A and reset at 0.4A, while also providing temperature protection for a maximum of 10,000 cycles. This device has a low temperature coefficient and a maximum operating temperature of 85℃, and can perform in a wide range of environments, from low-tension networks to high-pressure, electrical-discharge machinery.

The RHE070 is a great choice for equipment requiring short-circuit protection as it provides a cost-effective solution that offers low power consumption and longer service life than other fuses. The resettable characteristics and temperature-sensitive designs makes the RHE070 suitable for use in a wide range of applications and industries.

Overall, the RHE070 is an outstanding device for low voltage protection, ensuring that any applications it is used for will run safely and efficiently. Its wide range of features make it an ideal choice for protecting equipment from the risks associated with overload, short-circuiting, and temperature sensitivity.
