The BUSSMANN FWH-350A is a North Americanโstyle high-speed (fast-acting) semiconductor fuse for protecting rectifiers, inverters, and DC common-bus rails in UPS and power-electronic systems. This listing features reclaimed, continuity-tested units removed from decommissioned, fully functional equipment.
High-Speed Protection:
Fast-acting element tailored for semiconductor circuits with tight let-through limits.
Stud-Mount Cartridge Body:
Bolt-down blade terminals for robust, low-impedance connections and easy service.
High Interrupt Ratings:
1000ย Vย AC / 800ย Vย DC series rating with 200ย kA AC and 50ย kA DC interrupt capability.
Reclaimed & Verified:
Every unit is continuity-tested and visually inspected; OEM-new stock available by request.
