3NA6817-4 SIEMENS

The 3NA6817-4 is a low-voltage High Rupturing Capacity (HRC) fuse element designed and manufactured by Siemens. It belongs to the NH000 size category, a standardized dimension for easy interchangeability. This fuse is rated for a current of 40 Amperes (In: 40 A), making it suitable for protecting circuits with a nominal current draw of up to 40A. It features a gG characteristic, indicating it provides full-range protection against both overload and short-circuit currents. The fuse is designed for an AC voltage rating of 400V (Un AC: 400 V), commonly found in industrial and commercial power distribution systems. A combined indicator visually signals when the fuse has blown, simplifying troubleshooting and reducing downtime. The insulated grip lugs ensure safe handling during installation and replacement, minimizing the risk of electrical shock. This HRC fuse is ideal for protecting cables, equipment, and personnel from the damaging effects of overcurrents in a variety of applications. Its robust design and reliable performance make it a crucial component for maintaining electrical safety and system integrity. Siemens is a trusted name in electrical protection, ensuring high quality and adherence to international standards.
