The Siemens 3NA78300RC is an HRC fuse from the Siemens 3NA DIN fuse range, designed for dependable protection against overload and short-circuit conditions in industrial electrical 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 power distribution and electrical protection applications.
HRC fuses are commonly used where reliable interruption of high fault currents is required. The Siemens 3NA78300RC can be considered for industrial distribution panels, control panels, machinery, cable protection, power distribution systems and OEM electrical installations when correctly selected and coordinated with the overall protection system.
Its DIN-based design makes it suitable for compatible fuse systems using standardized industrial protection components. The high breaking capacity can make it appropriate for installations with potentially high prospective short-circuit currents.
For correct application, always verify the complete electrical requirements, including rated voltage, operating current, prospective short-circuit current, installation conditions, fuse characteristics and coordination with upstream and downstream protective devices.
