Product Description

Siemens 3NA71220RC HRC Fuse – DIN 3NA, 500 V AC, Up to 800 A, 120 kA

The Siemens 3NA71220RC is an HRC fuse from the Siemens 3NA DIN fuse range, designed for dependable overload and short-circuit protection in industrial electrical and power distribution systems. With a rated voltage of 500 V AC, a current rating of up to 800 A, and a short-circuit breaking capacity of 120 kA, it is suitable for demanding industrial electrical protection applications.

This Siemens DIN HRC fuse can be considered for industrial distribution panels, electrical control panels, machinery, cable protection, power distribution equipment and OEM electrical installations where reliable interruption of high fault currents is required. When correctly selected and coordinated with the complete protection system, it helps protect electrical circuits and connected equipment against overload and short-circuit conditions.

The 3NA DIN HRC fuse range is intended for compatible industrial fuse systems and high fault-current protection applications. Proper selection should consider operating current, rated voltage, prospective short-circuit current, installation conditions and coordination with other protective devices.
