PTC Resettable Fuses are a type of current-limiting device that trips when a current overload or short-circuit failure occurs, which allows the device to be repeatedly used after the fault condition has been corrected. The YQD120N0010 is a high-performance, single-phase, PTC Resettable Fuse designed specifically for three-phase AC power systems up to 690 volts. It is designed with an internal thermal fuse and does not require a current-limiting external resistor, making it a cost-effective solution for short-circuit protection and temporary overload protection applications.

The YQD120N0010 PTC Resettable Fuse has a wide range of applications, primarily in three-phase AC power supplies up to 690 volts. It is used primarily in power monitor systems, power distribution networks, DC/AC inverter systems and UPS systems. It is also used to provide short-circuit and overload protection in applications such as industrial equipment, motor drives and computers.

The YQD120N0010 PTC Resettable Fuse is a device that uses a temperature-sensitive material to open or close a circuit when subjected to a fault current or overload. When the device is subjected to a current exceeding its rated current, the temperature-sensitive material melts, causing the device to disconnect from the circuit and interrupt the flow of current.

The YQD120N0010 PTC Resettable Fuse has several features that make it an ideal device for short-circuit and overload protection. It provides instantaneous protection against over-currents up to 8.0 times its rated current and against short-circuits up to 13.3 times its rated current. The device has a short recovery time, typically between 6 and 9 seconds, and offers a high level of voltage withstand capabilities up to 690 volts. The device is resistant to shock, vibration, and temperature changes, and has a wide operating ambient temperature range between -40°C to 125°C. It is also designed with a long life cycle, typically between 100,000 and 200,000 operations.

The YQD120N0010 PTC Resettable Fuse is a simple and effective device for protecting three-phase AC power systems. Its integrated thermal fuse allows for low-cost, economical use and provides efficient and reliable protection against short-circuit and overload conditions. The device is designed for long life and has an extensive ambient temperature range, making it suitable for many industrial applications. By using the YQD120N0010 PTC Resettable Fuse, manufacturers can be assured of reliable short-circuit and overload protection for their three-phase AC power systems.
