Bussmann FWH-300A High Speed Semiconductor Fuse

FWH-300A High Speed Semiconductor Fuse from Bussmann (Eaton Bussmann series) is a North American style, cartridge‑body protection device designed for semiconductor circuits. This 300 A fast‑acting fuse protects power electronics by interrupting fault currents quickly, with a voltage rating up to 1000 VAC and 800 VDC and an interrupting rating of 200 kAIC at 1000 VAC (50 kAIC at 500 VDC). The unit is non‑indicating and UL Recognized, CSA and CE listed, making it suitable for industrial equipment and other applications that require robust protection for high‑current semiconductor loads. The FWH-300A is intended for use in power supplies, inverters, and other high‑current applications where rapid fault isolation minimizes damage to protected circuitry. It is part of the FWH high‑speed fuse family and is designed to meet North American protection standards while fitting into standard protection schemes. Always verify termination type and packaging with the supplier's datasheet to ensure proper compatibility with your assembly.
