The Siemens 3NA78240RC is an HRC fuse from the Siemens 3NA DIN fuse range, designed for reliable protection against overload and short-circuit conditions 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 protection applications.
The fuse can be considered for industrial distribution panels, control panels, machinery, cable protection, power distribution systems and OEM electrical installations where reliable high-fault-current interruption is required. When properly selected and coordinated, an HRC fuse helps protect electrical circuits and connected equipment from potentially damaging fault currents.
The Siemens 3NA DIN fuse family is intended for compatible industrial fuse systems. Before installation, the complete electrical requirements should be checked, including rated voltage, operating current, prospective short-circuit current, installation conditions and coordination with upstream and downstream protective devices.
The Siemens 3NA78240RC can be considered for:
