Eaton FWH-225A FWH high speed fuse - UL Recognized
Part Number: FWH-225A
Quick Summary
The Eaton FWH-225A high-speed fuse protects power circuits in industrial automation, delivering fast interruption for motor drives and control panels. In demanding electrical protection environments, selecting a fuse that lags on fault current can cause nuisance trips and costly downtime. This device is UL Recognized, CSA Certified, and CE marked RoHS compliant, aligning with global safety and environmental standards. For engineers you can rely on consistent protection without overselecting components; its 225A RMS rating and 200 kAIC interrupt capacity at 1000 Vac support robust protection in mixed AC/DC systems. The non-indicating fuse works with blade-end connections or stud mounting, offering installation flexibility and reduced total cost of ownership.

225A RMS current rating with a 1000 Vac and 800 Vdc voltage range delivers fast fault clearance, protecting critical loads from damaging overloads. This translates to reduced downtime, lower repair costs, and safer equipment operation on automated lines. Ideal applications include motor drives, inverters, and power feeders in control panels and switchgear, where rapid interruption is essential to maintain line continuity. Interrupt rating of 200 kAIC at 1000 Vac provides rugged fault isolation, allowing protection for high-energy systems without nuisance tripping under transient events. Business impact: greater system reliability and longer equipment life with fewer arcing incidents. Applications: data-center, manufacturing, and process lines with mixed AC/DC sections. Connection options Blade end x blade end with stud mounting offer installation flexibility. This means you can deploy the fuse in compact enclosures or on equipment frames without reworking hardware. The result is faster installation, fewer part numbers, and a lower total cost of ownership. Compliance and certifications UL Recognized, CSA Certified, CE RoHS Compliant ensure global acceptance. Benefit: simplifies cross-border procurement and regulatory compliance; application: multinational facilities and OEMs. Power loss of 39 W minimizes heat within control panels, improving thermal management and energy efficiency; non-indicating design reduces visual clutter while external diagnostics can monitor fuse status as needed.

FAQs
The FWH-225A supports blade end x blade end connections and also provides stud mounting, enabling flexible on-panel installation in tight cabinets or open-frame assemblies. Its Bussmann series lineage ensures compatibility with standard Eaton protection schemes, reducing the need for custom adapters and accelerating panel build times.
The fuse provides 225A RMS with a voltage rating of 1000 Vac and 800 Vdc. It offers an interrupt rating of 200 kAIC at 1000 Vac and 50 kAIC at 500 Vdc, supporting robust fault isolation in high-energy systems while limiting downstream damage.
Yes. The FWH-225A is UL Recognized and CSA Certified, with CE marking and RoHS compliance. This combination supports global procurement, regulatory adherence, and reduced compliance risk across multinational manufacturing environments.
Best-suited applications include motor drives, power feeders, and control-panel protection within automated lines. Its high interrupt capacity and wide voltage tolerance make it effective in mixed AC/DC systems, delivering reliable protection for critical load points while supporting scalable, compliant industrial architectures.
The FWH-225A is non-indicating, meaning there is no built-in visual status indicator. For monitoring, rely on external panel indicators or system diagnostics to flag faults. Regular replacement on a preventive maintenance schedule, aligned with system fault history and manufacturer guidance, helps sustain protection performance.
