Sinofuse RS308-HB-2G160A Fuse, 160A 1000VAC/750VDC, aR Fast-Acting Bolt-on, Size 2G - Pack of 10

High-Current Semiconductor Protection Fuse for Industrial Power & EV Systems

The Sinofuse RS308-HB-2G160A is a high-capacity, high-speed bolt-on fuse designed for the rigorous demands of power semiconductor protection. With a substantial 160A current rating within the compact Size 2G form factor, this fuse is an ideal solution for shielding high-power electronics such as industrial inverters, large-scale battery energy storage systems (BESS), and Electric Vehicle (EV) fast-charging infrastructure.

As an aR utilization category fuse, it is specifically optimized for partial-range short-circuit protection. The RS308-HB series is engineered to provide ultra-fast clearing of fault currents, which minimizes the let-through energy to downstream components. This prevents thermal overload and explosive failure in sensitive power semiconductors like IGBTs, MOSFETs, and thyristors. The Size 2G design utilizes heavy-duty bolt-on terminals to ensure high mechanical stability and low contact resistance, even in high-vibration or high-temperature operating environments.

Key Features:

• Precision Semiconductor Protection: Optimized aR-class performance ensures rapid response to short-circuit events, safeguarding delicate power electronics.
• Dual-Voltage Capability: Rated for 1000V AC and 750V DC, making it highly versatile for renewable energy systems and DC power distribution.
• Compact High-Current Design: The Size 2G bolt-on configuration provides a high current density (160A), saving space in dense electrical cabinets and power modules.
• Superior Fault Isolation: Features a high breaking capacity of 50kA, ensuring the safe interruption of high-energy fault currents without sustaining external damage.
• Industry-Leading Compliance: Built and tested in accordance with IEC 60269-4 and UL 248-13 standards, guaranteeing reliability for B2B industrial and automotive applications.
