Sinofuse RS308-HB-4G16A Fuse, 16A 1000VAC/750VDC, aR Fast-Acting Bolt-on, Size 4G - Pack of 10

Ultra-Fast Semiconductor Protection Fuse for Precision Power Systems

The Sinofuse RS308-HB-4G16A is a high-speed bolt-on fuse engineered for the protection of power semiconductor devices. This component is specifically designed to provide high-performance short-circuit protection for sensitive electronic hardware, including rectifiers, inverters, and UPS systems. Given its low amperage rating and high voltage tolerance, it is an ideal choice for the protection of auxiliary circuits in electric vehicles (EV) and specialized industrial power conversion units.

As an aR-class utilization fuse, the RS308-HB series is optimized for high-speed response to overcurrent events. Its design focuses on minimizing let-through energy, which is critical for preventing thermal damage to semiconductor junctions during a fault. The Size 4G round-body design with bolt-on tabs provides a rugged and secure installation, ensuring reliable low-resistance contact even in high-vibration or high-thermal-cycling environments.

Key Features:

• Precision High-Speed Protection: Specifically tuned as an aR utilization category fuse to offer ultra-fast interruption for semiconductor-based electronics.
• High Voltage Versatility: Rated for 1000V AC and 750V DC, making it suitable for modern high-voltage battery systems and international industrial power grids.
• Secure Bolt-on Mounting: The 4G hardware configuration ensures mechanical durability and electrical stability, preventing loss of contact in demanding industrial settings.
• Robust Interrupting Capacity: Capable of safely breaking fault currents up to 50kA, providing a high safety margin for professional-grade power applications.
• Certified Reliability: Engineered in accordance with international safety standards, including IEC 60269-4 and UL 248-13, ensuring global compliance and technical excellence.
