Eaton FWH-025A6FR high speed fuse - UL/CSA
Part Number: FWH-025A6FR
Quick Summary
Eaton FWH-025A6FR high speed fuse protects electrical circuits in industrial controls and motor drives. Engineers often struggle with nuisance trips and selecting the correct amp rating for mixed loads and variable fault currents. UL and CSA listings, plus CE RoHS compliance, validate safety and regulatory acceptance across regions, while the 50 kAIC interrupt rating provides robust fault containment. Designed for ferrule-end terminations, this device supports standardized panel protection and straightforward field installation, reducing commissioning time. Coupled with Eaton’s spec sheets and datasheets, it enables consistent part selection, easier qualification, and measurable uptime gains for manufacturing operations.

Feature: The FWH-025A6FR delivers a 25A RMS amperage rating with a 50 kAIC interrupt capacity at 20% pf. This fast-acting behavior minimizes fault energy and helps prevent damage to downstream components in drives and feeders. Application: Use in industrial control panels, motor drives, and equipment feeders where fast clearance reduces downtime. Business impact: Improves system reliability, supports tighter short-circuit budgets, and aligns with industrial protection standards. Feature: 500 VAC/DC voltage rating and a ferrule-end 6x32mm construction. This ensures compatibility with common industrial fuse blocks and enables quick, repeatable field replacements. Application: Suitable for switchgear, power supplies, and mixed-voltage control circuits. Business impact: Streamlines installation and maintenance, reducing panel downtime and labor costs.

FAQs
Plan for ferrule-end terminations compatible with standard 6x32mm fuse blocks and ensure the panel supports a 1.25 inch long by 0.25 inch wide device. Since this is a non-indicating fuse, plan for separate status monitoring downstream. Use the provided catalog and datasheet to confirm mounting clearances and wiring practices recommended by Eaton.
The device is rated for 25A RMS with a 50 kAIC interrupt capacity at 20% power factor and a voltage rating of 500 VAC/DC (35-800 A only). These specs indicate rapid fault clearance with high fault-current tolerance, protecting downstream equipment such as motors, drives, and feeders while maintaining safe voltage handling in mixed systems.
Yes. Its high-speed response, 25A RMS rating, and 50 kAIC interrupt capacity are well-matched for motor drive protection and other high-inrush applications. The ferrule-end construction and 1.25 in long body fit common drive and control panel assemblies, offering reliable fault clearance without compromising panel space or serviceability.
The fuse is UL and CSA listed and CE Marked RoHS Compliant. These certifications support compliance in global manufacturing environments and simplify supplier qualification, panel approvals, and customer audits.
