The BUSSMANN FWH-600A is a North American–style 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 on a Ø 2.000 in body for robust, low-impedance connections.
High Interrupt Ratings:
500Â VÂ AC / 500Â VÂ DC with 200Â kA AC RMS Sym and 50Â kA DC interrupt capability.
Reclaimed & Verified:
Every unit is continuity-tested and visually inspected; OEM-new stock available by request.
