FAQs
The FWA-70BASI1 is part of the Eaton Bussmann series and is designed for standard electrical protection in industrial panels, including motor control centers and distribution boards. It integrates with existing Bussmann-series protection schemes, enabling straightforward cross-compatibility and simplified stocking for service teams. When upgrading legacy panels, verify the catalog number and packaging to ensure fit and interchangeability with existing fuse blocks.
This fuse is rated for 150 A with a voltage rating of 250 (per catalog data). It is a high speed fuse intended to interrupt fault currents quickly to minimize damage to downstream equipment. Although the data lists a non-indicating variant, ensure your control system’s diagnostics align with your panel’s fault-clearing strategy, and consult the factory if layout or certification requires indicating versions.
Yes, the high speed protection and 150 A rating make it appropriate for motor feeds and automation circuits where fast fault interruption preserves drive electronics and minimizes downtime. For CNC and similar loads, verify inrush tolerance and consult the catalog to confirm compatibility with your drive’s protection settings and any required coordination with upstream breakers.
RoHS compliance is listed for the FWA-70BASI1 with factory confirmation available for other certifications. For projects requiring CE or IP-related certifications, contact the factory to verify available configurations or lead times. Always document RoHS conformance in your bill of materials to ensure regulatory alignment across manufacturing sites.
The non-indicating design reduces visual maintenance overhead, while the standard packaging improves stocking efficiency and replacement speed. ROI benefits accrue from reduced downtime due to faster fault clearance, easier inventory management within Bussmann series products, and lower total cost of ownership over lifecycle maintenance in industrial facilities.
