Siemens LV HRC

The Siemens LV HRC Series consists of high‑rupturing‑capacity (HRC) fuses and associated components used in low‑voltage power systems. These include DIN‑type fuse links (e.g. the 3NA range), fuse bases, fuse switch‑disconnectors, isolating links, signal detectors, and versions with front indicators. They are rated for voltages up to about 500‑690 VAC, currents from a few amperes up to several hundred amps, with high short‑circuit breaking capacity (e.g. 120 kA). The series protects cables, lines, switchboards, power distribution networks and motor circuits in industrial, commercial and utility installations.
