3NA7140-6 SIEMENS

The 3NA7140-6 is a low-voltage High Rupturing Capacity (HRC) fuse element designed and manufactured by Siemens. It belongs to the NH1 size category, a standardized form factor for easy installation and replacement in compatible fuse bases and holders. This fuse is rated for a current of 200 Amperes (In: 200 A), making it suitable for protecting circuits and equipment from overcurrents up to this level. It features a gG characteristic, indicating its full-range protection capability, effectively safeguarding against both overload and short-circuit currents. The fuse is designed for AC systems with a voltage rating of up to 690 V (Un AC: 690 V) and DC systems up to 440 V (Un DC: 440 V), providing versatile application possibilities. A combined indicator visually signals the fuse's operational status, simplifying troubleshooting and maintenance. The live grip lugs facilitate safe and convenient handling during installation and removal, minimizing the risk of electrical shock. This HRC fuse ensures reliable and robust protection for electrical installations and equipment against damage caused by overcurrents.
