Bussmann — SPP-6K800 800A / 700VAC High-Speed Semiconductor Fuse — Reclaimed

High-Speed Semiconductor Fuse  •  800A  •  700VAC  •  aR  •  P/N SPP-6K800

The Bussmann SPP-6K800 is a heavy-duty, high-speed semiconductor fuse rated at 800 amps and 700 VAC. Designed for protection of high-power semiconductor circuits, this square-body fuse provides rapid interruption of damaging fault currents to help protect sensitive rectifier, inverter, drive, and power-conversion components.

The SPP-6K800 is marked aR, identifying it as a partial-range high-speed fuse intended specifically for semiconductor protection. This type of fuse is designed to limit damaging fault energy in power-electronic circuits where conventional general-purpose fuse protection may not provide sufficiently fast response.

This listing is for a reclaimed component removed from decommissioned power equipment. Each unit is continuity-tested and visually inspected prior to sale. Cosmetic wear, discoloration, surface marks, or other signs of previous installation may be present and are normal for reclaimed industrial components.

800A / 700VAC Semiconductor Protection:
The SPP-6K800 is rated at 800 amps and 700 volts AC and carries an aR semiconductor-protection designation. The fuse is also identified as 2GU/50 and is part of the Bussmann SPP-6 family.

Features

High-Speed Semiconductor Protection:
Designed for power-electronic circuits where rapid interruption of excessive fault current is critical to protecting semiconductor components.

800 Amp Current Rating:
Heavy-duty high-current fuse designed for demanding industrial and critical-power applications.

700 VAC Rating:
Designed for compatible high-power AC electrical and power-electronic circuits with a fuse voltage rating of 700 VAC.

aR Utilization Category:
Partial-range semiconductor fuse designed for high-speed short-circuit protection of sensitive power semiconductors.

Low Electrical Resistance:
The actual fuse label specifies 0.0940 mΩ at 21°C.

Square-Body Construction:
Heavy-duty industrial construction designed for high-current semiconductor and power-conversion applications.

Reclaimed & Verified:
Removed from decommissioned equipment, visually inspected, and continuity-tested prior to sale.

Reclaimed Part Condition

This product is a reclaimed industrial component removed from decommissioned equipment. Units are continuity-tested and visually inspected prior to sale. Because these are previously installed components, cosmetic condition will vary and may include surface discoloration, scratches, oxidation, mounting marks, label wear, or other evidence of prior service. These cosmetic differences do not necessarily indicate an electrical defect.

Compatibility

The SPP-6K800 should be used only in equipment designed to accept this fuse or an approved equivalent. Semiconductor fuse selection depends on the equipment manufacturer’s required electrical characteristics, mechanical configuration, fault-current performance, and semiconductor-protection requirements.

Applications may include compatible UPS systems, rectifiers, inverters, industrial drives, converters, and other high-power semiconductor equipment. Always verify the original fuse part number or equipment bill of materials before ordering.

Important Compatibility Note

High-speed semiconductor fuses must be matched to the equipment manufacturer’s specified part number, amperage, voltage, utilization category, physical configuration, and semiconductor-protection characteristics. Do not substitute a fuse based solely on matching current and voltage. Verify SPP-6K800 against the original fuse or equipment service documentation before ordering or installation.
