3NA7140 SIEMENS

The 3NA7140 from Siemens is a low-voltage High Rupturing Capacity (HRC) fuse element, specifically designed for NH1 fuse systems. It provides reliable overcurrent protection for electrical installations and equipment. This fuse is rated for a current of 200 Amperes (In: 200 A) and features a gG characteristic, making it suitable for general-purpose applications, protecting against both overload and short-circuit currents. The 3NA7140 is designed for AC systems with a voltage rating of up to 500 V (Un AC: 500 V) and DC systems up to 440 V (Un DC: 440 V). It incorporates a combined indicator that visually signals when the fuse has blown, simplifying troubleshooting and maintenance. The fuse also includes live grip lugs, enhancing safety during installation and removal by providing a secure and insulated gripping point. Siemens HRC fuses are known for their high breaking capacity and current limiting capabilities, ensuring effective protection of downstream equipment. This fuse is ideal for use in industrial, commercial, and residential applications where reliable and robust overcurrent protection is essential. Its compact design and ease of installation make it a versatile solution for a wide range of electrical protection needs.
