3NA3144-6 SIEMENS

The 3NA3144-6 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 250 Amperes, making it suitable for applications with high current demands. 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 rated for an AC voltage (Un AC) of 690V and a DC voltage (Un DC) of 440V, ensuring compatibility with various electrical systems. A front indicator is integrated into the fuse design, providing a visual indication of the fuse's status, allowing for quick identification of blown fuses. The live grip lugs facilitate safe and easy installation and removal of the fuse, minimizing the risk of electrical shock. This HRC fuse is ideal for use in industrial, commercial, and residential applications where reliable and effective circuit protection is essential. Siemens' 3NA3144-6 fuse offers a robust solution for safeguarding electrical systems against damage caused by overcurrents.
