The BUSSMANN SPP-6K800 is a Semitron™ series, high-speed (aR) square-body fuse for semiconductor protection. The “6K” code denotes a case size 6, stud-mount style fuse. It’s widely used in UPS common-bus rails, rectifiers, and inverter stacks to limit fault energy and protect power semiconductors. This listing is for reclaimed, continuity-tested units removed from decommissioned equipment.
High-speed aR performance:
Engineered for rapid interruption and low let-through I²t in semiconductor circuits.
Stud-mount Square-Body:
Case size 6 “K-style” (stud) body; 2GU/50 mounting pattern for robust, low-impedance installation.
700 V class rating:
700 VAC series rating with high AC interrupting capability; UL Recognized (UR) aR fuse class.
Reclaimed & verified:
Each fuse continuity-tested and visually inspected; OEM-new stock available on request.
