Eaton FWH-70A High Speed Fuse - 700 Vac/dc, RoHS
Part Number: FWH-70A
Quick Summary
The Eaton FWH-70A high speed fuse provides fast overcurrent protection for 700 Vac/dc circuits in industrial control panels. Engineers often struggle with nuisance trips and downtime caused by slower fusing in motor drives and power rails. This device is RoHS compliant, and regional CE/UL verification should be confirmed with Eaton to satisfy your regulatory requirements. Its blade-end x blade-end connection and compact enclosure simplify installation in densely packed control panels, reducing maintenance time and service calls. Sourcing from the Bussmann series ensures consistent availability, streamlined cross-references, and predictable performance across your electrical protection and circuit control portfolio.
