3NA6120-4 SIEMENS

The 3NA6120-4 is a low-voltage High Rupturing Capacity (HRC) fuse element designed and manufactured by Siemens. It is an NH1 size fuse, commonly used for protecting electrical circuits and equipment from overcurrents and short circuits. This fuse has a rated current (In) of 50 Amperes, indicating the maximum current it can continuously carry without tripping. It features a gG characteristic, signifying its suitability for general-purpose applications, providing protection against both overload and short-circuit currents. The fuse is designed for an AC voltage (Un AC) of 400V, making it compatible with standard low-voltage power systems. It incorporates a combined indicator, visually signaling when the fuse has blown, simplifying fault diagnosis and reducing downtime. The insulated grip lugs ensure safe and easy handling during installation and replacement, minimizing the risk of electrical shock. Siemens HRC fuses are known for their reliable performance and high breaking capacity, effectively interrupting fault currents to prevent damage to equipment and ensure safety. This fuse is ideal for use in industrial, commercial, and residential applications where reliable overcurrent protection is essential. The 3NA6120-4 fuse provides robust protection, enhancing the safety and reliability of electrical installations.
