Sinofuse RS308-HB-2G180A Fast-Acting Fuse, 180A 250VAC/170VDC, aR Semiconductor Protection, Bolt-on Type - Pack of 10

High-Speed Semiconductor Protection Fuse for Industrial Applications

The Sinofuse RS308-HB-2G180A is a professionally engineered, fast-acting bolt-on fuse designed for high-performance circuit protection. Specifically categorized under the aR utilization category, it provides partial-range protection for semiconductor devices, including rectifiers, inverters, and high-power converters. Its design focuses on extreme speed to isolate faults, minimizing the let-through energy to protect sensitive components like IGBTs and thyristors.

This fuse is built to withstand rigorous industrial environments, featuring a high breaking capacity of 80kA at 250VAC and 50kA at 170VDC. The Size 2G housing utilizes a secure bolt-on terminal structure (M6), ensuring minimal contact resistance and stability under mechanical vibration, making it suitable for electric vehicle (EV) charging infrastructure and energy storage systems (ESS).

Key Features:

• Optimized Semiconductor Guard: Engineered for ultra-fast response times to protect power electronics from high-energy short-circuit faults.
• Dual-Voltage Versatility: Reliable performance across 250VAC and 170VDC power bus architectures.
• Robust Bolt-on Mounting: Designed for Size 2G configurations with M6 bolt compatibility, providing a heavy-duty electrical and mechanical connection.
• Safety Compliance: Meets international standards including IEC60269-4, UL248-13, and is RoHS compliant, ensuring global applicability and environmental safety.
• Thermal Management: Optimized low power dissipation (13.1W @ In) to ensure cool operation within dense power distribution panels.
