Sinofuse RS308-HB-4G32A Fuse, 32A 1000VAC/750VDC, aR Fast-Acting Bolt-on, Size 4G - Pack of 10

High-Performance Semiconductor Protection Fuse for Industrial Power Electronics

The Sinofuse RS308-HB-4G32A is a specialized high-speed bolt-on fuse designed for the protection of power semiconductor devices. As part of the globally recognized RS308 series, this fuse is engineered to safeguard critical components such as IGBTs, thyristors, and bridge rectifiers in high-voltage environments. It is ideally suited for integration into electric vehicle (EV) charging infrastructure, power conversion systems, and DC link protection.

Featuring an aR utilization category, the RS308-HB series provides ultra-fast short-circuit response. This characteristic is vital for limiting let-through energy, ensuring that fault currents are interrupted before sensitive electronic circuitry sustains permanent damage. The Size 4G construction provides a robust round-body design with integrated bolt-on terminals, offering high mechanical durability and low contact resistance for demanding industrial applications.

Key Features:

• Ultra-Fast Semiconductor Protection: Optimized aR-class performance specifically designed to handle the fast-rising fault currents found in modern power electronics.
• Dual-Voltage Capability: Fully rated for both 1000V AC and 750V DC applications, providing versatile circuit design possibilities for complex power systems.
• Secure Bolt-on Installation: The Size 4G mounting configuration ensures a stable electrical connection that is resistant to high vibration and thermal shock.
• Superior Interruption Rating: Provides a high breaking capacity of 50kA, ensuring safe isolation of fault conditions in high-energy circuits.
• International Safety Standards: Compliant with IEC 60269-4 and UL 248-13, ensuring rigorous quality control and technical reliability for global markets.
