The Siemens 3NA78320RC is an HRC fuse from the Siemens 3NA DIN fuse range, designed for dependable protection of electrical installations against overload and short-circuit conditions. 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 power distribution and electrical protection applications.
HRC fuses are widely used in industrial electrical systems because they provide reliable interruption of high fault currents when correctly selected and coordinated. The Siemens 3NA78320RC can be considered for power distribution panels, industrial control panels, machinery, cable protection, factory electrical systems and OEM installations.
The DIN-based design makes this fuse suitable for compatible fuse systems designed around standardized industrial protection components. Its high short-circuit breaking capacity makes it appropriate for electrical installations where the prospective fault current can be substantial.
For proper application, always verify the complete system requirements, including rated voltage, operating current, prospective short-circuit current, installation conditions, fuse characteristics and coordination with upstream and downstream protective devices.
