The BUSSMANN FWH-150A 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 for low-impedance, robust connections in compact layouts.
High Interrupt Ratings:
500Â V AC/DC with 200Â kA AC RMS Sym interrupting rating and 50Â kA DC capability.
Reclaimed & Verified:
Every unit is continuity-tested and visually inspected; OEM-new stock available by request.
