Sinofuse RS308-HB-2G100A Fuse, 100A 1000VAC/750VDC, aR Fast-Acting Bolt-on, Size 2G - Pack of 10

High-Capacity Industrial Semiconductor Protection Fuse

The Sinofuse RS308-HB-2G100A is a high-performance, high-speed bolt-on fuse tailored for the protection of power semiconductor devices in heavy-duty electrical systems. With a robust 100A current rating and a Size 2G body, this fuse is engineered for high-power applications including industrial rectifiers, large-scale UPS systems, EV battery management systems, and high-capacity motor drives.

Designed with an aR utilization category, the RS308-HB series is intended for the short-circuit protection of semiconductors. It features an ultra-fast response time to limit the let-through energy, effectively shielding sensitive power components such as high-current thyristors, diodes, and power modules from destructive fault currents. The bolt-on design provides a low-resistance interface and mechanical stability, making it suitable for environments prone to thermal expansion and mechanical vibration.

Key Features:

• High-Current Rapid Protection: Specifically designed with aR characteristics to provide ultra-fast interruption for high-amperage power circuits.
• Dual-Voltage Rating: Rated for up to 1000V AC and 750V DC, offering flexibility for diverse industrial power distribution networks and DC energy systems.
• Superior Thermal Management: Optimized for low power loss and minimal heat generation during continuous 100A operation, enhancing equipment lifespan.
• Standardized 2G Form Factor: The bolt-on mounting style ensures a secure connection to busbars, minimizing voltage drops and maintaining circuit integrity.
