Eaton Specification Sheet - FWH-100A
The FWH-100A delivers high-speed interruption at a 100 A rating, enabling rapid fault isolation. This reduces fault energy and arc flash risk, protecting downstream equipment and personnel. Applications include motor drives, power distribution panels, and automation equipment where fast clearing is critical. Its 1000 Vac / 800 Vdc ratings support AC/DC systems in industrial control panels, while stud mounting provides robust electrical and mechanical connection for secure panel installations. The rugged stud mount design also facilitates dependable long-term service in harsh industrial environments, reducing maintenance and replacement costs. This fuse’s compact form factor fits standard Bussmann series footprints, simplifying retrofits and new equipment design alike. RoHS compliance aids global procurement, while non-indicating operation minimizes visual complexity in control cabinets.

FAQs
The FWH-100A uses a stud mounting method, providing a robust, vibration-resistant connection ideal for heavy-duty control panels and power distribution enclosures. Its dimensions, including 4.6 in length, 1.8 in width, and 1.12 in height, fit standard Bussmann series footprints, enabling straightforward retrofits and reliable long-term installation with minimal platform modification.
The FWH-100A is rated for 100 A with a voltage rating of 1000 Vac and 800 Vdc. This makes it suitable for broad AC/DC protection in industrial automation, including power distribution circuits, motor drives, and control panels where fast clearing is essential to protect downstream equipment.
Yes, the FWH-100A is RoHS compliant according to Eaton’s compliance data. For other global certifications or regulatory requirements, consult Eaton’s datasheets or contact the factory to confirm availability of additional approvals tailored to your region and application.
Non-indicating means there is no local visual indicator on the fuse itself. This is advantageous in installations where status signaling is handled by external monitoring or control logic, reducing panel clutter and potential misinterpretation of fuse status in crowded enclosures.
When replacing, use the same FWH-100A 100 A rating and the same stud mounting format to preserve protection coordination. Refer to the Eaton datasheet for installation torque, compatible panel dimensions, and replacement intervals. Keeping spare Bussmann FWH series devices on hand minimizes downtime during routine maintenance or fault events.
