Eaton FWP-35 High Speed Fuse - 1400 Vac / 1000 Vdc
Part Number: FWP-35
Quick Summary
The Eaton FWP high speed fuse protects servo drives and power electronics by interrupting faults quickly in demanding industrial applications. Engineers often wrestle with nuisance trips and costly downtime when slower fuses fail to clear transient faults. Compliance considerations matter; verify with the factory for CE/UL-style conformance and any region-specific certifications. As part of the Eaton Bussmann series, this fuse supports standard packaging and non-indicating operation, helping you streamline panel design. In practice, you gain faster fault clearing, reduced downtime, and simpler sourcing across servo drives, motor controls, and power electronics. Rely on Eaton's documentation, such as the FWP-35 datasheet and catalogs, to validate installation parameters and ensure reliable protection in your equipment.

Feature: Ultra-fast interruption ensures faults are cleared in milliseconds, protecting drives and downstream circuits in industrial control systems as part of the Eaton Bussmann series high speed fuses. Business Impact: This minimizes arc damage and protects valuable equipment from transient faults, reducing unplanned downtime and boosting line availability for automation lines. Application: Particularly effective for servo drives, motor controllers, and power electronics in automation panels that demand reliable protection.Feature: Voltage rating versatility spans 1400 Vac (FWS 8-15 A), 2100 Vac (FWS 2-6 A), and 1000 Vdc (FWL/FWS 2-30 A), enabling flexible protection within the Bussmann series high speed fuses. Business Impact: Designers can standardize on a single family to cover diverse equipment classes, reducing BOM management and stocking costs. Application: Suitable for industrial drives, PLC-based control cabinets, and power supplies in manufacturing environments.Feature: Compact form factor delivers a 0.75 in square footprint with a height of 4.35 in, and standard packaging. Business Impact: The small footprint frees panel space, accelerates installation, and supports streamlined integration with common fuse clips. Application: Ideal for space-constrained panels and OEM assemblies in automation and control systems.Feature: Non-indicating operation simplifies installation and reduces BOM complexity, while maintaining reliable protection. Business Impact: Fewer indicators mean lower wiring and wiring errors, with predictable performance across replacements and upgrades. Application: Fits standard Bussmann series clips and standard packaging across replacement programs.Feature: Documentation and datasheets are available via Eaton catalogs and the FWP-35 specification sheet, supporting design validation. Business Impact: Access to up-to-date data accelerates verification, improves procurement timing, and minimizes design-change risks. Application: Engineers and buyers rely on these resources when qualifying protection strategies for automation equipment.Feature: Compliance status is manufacturer-stated and region-specific; confirm certifications with Eaton to ensure regulatory alignment. Business Impact: This reduces post-install audits and avoids delays due to unverified approvals. Application: Essential for projects requiring CE/UL-like conformance and rigorous regional compliance checks.

FAQs
The FWP-35 is designed for Bussmann series high speed fuses with the standard 0.75 in by 0.75 in cross-section and 4.35 in height. It fits common fuse clips and holders used in industrial panels. When selecting a holder, verify clip spacing and mounting clearance to ensure secure insertion and reliable contact under duty cycles typical for servo drives and power electronics.
voltage ratings vary by variant: 1400 Vac for FWS 8-15 A, 2100 Vac for FWS 2-6 A, and 1000 Vdc for FWL/FWS 2-30 A. Amperage rating depends on the chosen variant. Always cross-check the exact FWP-35 sub-model in Eaton’s catalog to confirm the correct combination of voltage and current for your application.
Yes. The FWP-35 is engineered for fast overcurrent protection in servo drives and motor control applications. Its high speed interrupt capability minimizes fault propagation, protecting downstream electronics and reducing downtime in automated systems.
Certification status for the FWP-35 is manufacturer-stated and region-specific. For official CE, UL, or other regulatory conformance, contact Eaton to obtain the current certification scope and documentation before compliance audits or customer engagements.
Eaton provides catalogs and datasheets for the FWP-35, including the Bussmann series catalog and the specification sheet. Use these resources to validate electrical ratings, dimensional data, and installation requirements, accelerating design reviews and procurement timelines.
