Bussmann FWP High-Speed Fuse, 700V AC/DC, Standard

Bussmann FWP High-Speed Fuse, 700V AC/DC, Standard

The Bussmann FWP High-Speed Fuse, 700V AC/DC, Standard is an Eaton Bussmann series fuse engineered for demanding overcurrent protection duty in power circuits. This FWP series carries a dual voltage rating of 700 Vac and 700 Vdc, giving specifiers a single fuse platform that can be applied to both AC and DC circuits without switching product lines. The fuse is offered in Standard speed construction, and the FWP series spans amp ratings from 80A through 450A — specifically 80A, 125A, 200A, 250A, 300A, and 450A — so the correct rating can be matched to the connected load and available fault current. Select the amp rating that fits your specific application from the options offered on this product page, and consult Eaton Bussmann documentation to confirm proper coordination with upstream and downstream protective devices.

Key Features

• Dual Voltage Rating: Rated 700 Vac and 700 Vdc, allowing the FWP series to protect both AC and DC power circuits with one fuse platform.
• Amp Rating Range: Available in 80A, 125A, 200A, 250A, 300A, and 450A ratings, so the fuse can be matched to the specific circuit load and application.
• High-Speed Fuse Construction: Standard speed FWP design engineered for fast-clearing overcurrent response and consistent time-current characteristics.
• Bussmann FWP Series: Part of the Eaton Bussmann FWP high-speed fuse series, providing a consistent, repeatable platform across the full amp rating range.
• Standard Speed Type: Configured as a Standard speed fuse within the FWP product line for applications that call for this speed classification.
• Single-Series Sourcing: Covering 80A to 450A under one series simplifies stocking and cross-referencing for electrical distributors and panel builders.
