The BUSSMANN FWP-250A is a North Americanโstyle high-speed (fast-acting) bolted-tag fuse engineered for reliable overcurrent protection in UPS and power-electronic systems. It safeguards rectifiers, inverters, and DC common-bus rails with low let-through energy. This listing features reclaimed, continuity-tested units removed from decommissioned, fully functional equipment.
High-Speed Protection:
Fast-acting element tailored for semiconductor applications with low Iยฒt.
Bolted-Tag Cartridge:
North American blade-end fuse body (non-indicating) for robust, low-impedance stud mounting.
AC / DC Capability:
Rated 700ย Vย AC with 200ย kA interrupt rating and DC use per datasheet (see specs).
Reclaimed & Verified:
Each unit is continuity-tested and visually inspected; OEM-new stock available by request.
