Eaton FWH-90A High Speed Fuse - 700 Vac/dc, 90 A
Part Number: FWH-90A
Quick Summary
Eaton FWH-90A high speed fuse protects electrical circuits in industrial controls and motor drives. Engineers rely on fast-acting devices to prevent equipment damage and downtime in high-current 700 Vac/dc systems. Note: The data sheet does not list SIL, CE, or IP certifications, but RoHS compliance supports environmental responsibility and regulatory alignment. The 90 A rating paired with stud mounting delivers rugged, field-friendly installation in control panels and power cabinets. This fuse simplifies procurement and minimizes panel redesigns by using standard Bussmann hardware and a compact footprint. Businesses benefit from reduced downtime, clearer fault localization, and predictable maintenance planning when protecting critical loads in automation and machinery.

FAQs
To install the FWH-90A, secure it using the stud mounting into a compatible fuse holder or terminal block designed for high-current Bussmann devices. Ensure clean, tight connections, proper insulation, and adherence to NEC guidelines. After mounting, verify continuity and confirm that the circuit protection settings match the 90 A rating before energizing the panel.
The FWH-90A is ideal for industrial control panels, motor drive circuits, and power distribution nodes that require fast fault interruption at 90 A and up to 700 Vac/dc. It pairs well with rugged process machinery, HVAC controls, and other high-current environments where reliable, rapid protection minimizes equipment damage and downtime.
The FWH-90A offers a high speed interrupt with a 700 Vac/dc rating and a 90 A current rating in a stud-mount package, enabling robust, vibration-tolerant installations. Its non-indicating design reduces panel clutter, while RoHS compliance supports regulatory and environmental requirements, making it suitable for modern automation environments.
Yes, the FWH-90A is RoHS compliant, meaning it meets environmental and materials restrictions that minimize hazardous substances. This helps ensure compliance with European and global sustainability standards, simplifies supplier audits, and supports greener manufacturing practices without compromising protection performance.
