3NA6140-4 SIEMENS

The 3NA6140-4 is a low-voltage High Rupturing Capacity (HRC) fuse element designed and manufactured by Siemens. It belongs to the NH1 size category, a standardized dimension for industrial fuses. This fuse is rated for a current of 200 Amperes (In: 200 A), making it suitable for protecting circuits with high current demands. 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 power distribution systems. A combined indicator visually signals the fuse's status, showing whether it is intact or has blown. The insulated grip lugs ensure safe handling during installation and replacement, minimizing the risk of electrical shock. These fuses are crucial components in electrical panels and distribution boards, safeguarding equipment and preventing damage from overcurrents. Siemens HRC fuses are known for their reliability and consistent performance in demanding industrial environments. They play a vital role in maintaining the safety and uptime of electrical systems.
