3NA6824-4KK SIEMENS

The 3NA6824-4KK is a low-voltage High Rupturing Capacity (HRC) fuse element designed and manufactured by Siemens. It belongs to the NH00 size, a standardized dimension for easy installation and replacement in compatible fuse bases and holders. This fuse is rated for a current of 80 Amperes (In: 80 A), making it suitable for protecting circuits and equipment from overcurrents up to this level. It features a gG characteristic, indicating it provides full-range protection for general applications, safeguarding against both overload and short-circuit currents. The fuse is designed for an AC voltage rating of 400V (Un AC: 400 V), ensuring compatibility with standard low-voltage power systems. A combined indicator is integrated into the fuse, providing visual confirmation of the fuse's operational status, simplifying troubleshooting and maintenance. The fuse is equipped with insulated grip lugs, enhancing safety during installation and removal by preventing accidental contact with live parts. These grip lugs also facilitate easy handling and replacement of the fuse. The 3NA6824-4KK fuse element is commonly used in industrial, commercial, and residential applications to protect electrical circuits, motors, transformers, and other sensitive equipment from damage due to overcurrents.
