Industrial FWH-800A Semiconductor Fuse

FWH-800A is a high‑speed semiconductor fuse from Eaton’s Bussmann series designed to protect power semiconductors in DC and AC power systems. This 6×32 mm, stud‑mount cartridge fuse is rated for 800 A and provides 500 VAC and 500 VDC operation with a non‑indicating package, making it suitable for high‑current protection in DC buses, motor drives, power converters, and rectifier assemblies. It offers an interrupting rating of up to 200 kA at AC and 50 kA at DC, and carries UL Recognized along with CSA and CE certifications, reflecting its suitability for demanding industrial applications. The FWH‑800A is a very fast acting fuse in the FWH family, purpose‑built to quickly clear faults in semiconductor paths while minimizing collateral system disruption.
