PTC Resettable Fuses

The RUSBF160-2 is a type of PTC (positive temperature coefficient) resettable fuse. It comes in a compact, lightweight, and semiconductor-based design that uses polymer tantalum materials and proprietary thermal arc-rated construction. This allows the fuse to protect and reset itself whenever current is overloaded. In addition, the RUSBF160-2 is a multifunctional device, able to detect a broad range of temperatures, aging delays, and product lifetime cycling.The most common applications for the RUSBF160-2 are in system resets, power supplies, consumer electronics, power utilization, and industrial control. In system resets, the fuse helps protect circuits against power and data loss due to overcurrent. In power supplies, it can help protect against overvoltage and against over-temperature conditions. In consumer electronics, it can help protect against damage and short circuits caused by unbalanced power draws. In power utilization, the fuse can serve as a power protection system for critical circuitry. Finally, in industrial control, the device helps protect from short circuits and from the accumulation of dust particles.The working principle of the RUSBF160-2 is that it acts as an overload control device, providing precise thermal protection against electrical faults. When the current reaches an overload level, the thermal properties of the PTC material are activated to shut off the circuit, safely resetting it. Once the current has dissipated, the PTC fuse will slowly reset itself to full power. This process helps protect sensitive equipment and prevent further damage due to overcurrent.The RUSBF160-2 is also designed to provide flexible mounting options. The device can be mounted on DIN rail, circuit boards, or copper tracks. This makes the device highly suitable for a wide range of applications and helps reduce the installation and maintenance costs associated with using traditional thermal-protection devices.Overall, the RUSBF160-2 is an effective and reliable PTC resettable fuse. It offers precise thermal protection and control, while its flexible mounting options allow for a wide range of applications. Whether it’s used for system resets, power utilization, consumer electronics, or industrial control, the RUSBF160-2 is a durable and reliable PTC fuse for today’s current-protection needs.
