3NA7830-7 SIEMENS

The 3NA7830-7 is a low-voltage High Rupturing Capacity (HRC) fuse element designed and manufactured by Siemens. It belongs to the NH00 size category, a standardized dimension for easy interchangeability. This fuse is rated for a current of 100 Amperes (In: 100 A), making it suitable for protecting circuits with a nominal current draw up to this value. It features a gG characteristic, indicating it provides full-range protection against both overload and short-circuit currents. The fuse is designed for AC systems with a voltage rating of 500V (Un AC: 500 V) and DC systems with a voltage rating of 250V (Un DC: 250 V). A combined indicator visually signals when the fuse has blown, simplifying fault diagnosis. The fuse also incorporates live grip lugs, facilitating safe installation and removal using specialized fuse pullers. This HRC fuse is ideal for protecting electrical equipment and systems in industrial, commercial, and residential applications, ensuring reliable and safe operation. Its robust design and clear indication features contribute to minimizing downtime and enhancing safety.
