3NA7817-6 SIEMENS

The 3NA7817-6 is a low-voltage High Rupturing Capacity (HRC) fuse element designed and manufactured by Siemens. It belongs to the NH00 size, a standardized dimension for easy interchangeability. This fuse is rated for a current of 40 Amperes (In: 40 A) and is designed for general-purpose (gG) applications, providing protection against both overload and short-circuit currents. It is suitable for AC systems up to 690 Volts (Un AC: 690 V) and DC systems up to 250 Volts (Un DC: 250 V). The fuse features a combined indicator, visually signaling when the fuse has blown, simplifying maintenance and troubleshooting. Equipped with live grip lugs, it ensures safe handling during installation and replacement, minimizing the risk of electrical shock. This HRC fuse provides reliable and effective protection for electrical circuits and equipment against overcurrents. Its robust design and high breaking capacity make it suitable for a wide range of industrial and commercial applications. The 3NA7817-6 fuse is an essential component for ensuring the safety and reliability of electrical installations.
