Siemens LV HRC Fuse Element 3NA6824-7
Overview
LV HRC fuses are used for installation systems in non-residential, commercial and industrial buildings as well as in systems of power supply companies. They therefore protect essential building parts and plants.
LV HRC fuses are fuse systems designed for operation by experts. There are no constructional requirements for non-interchangeability of rated current and touch protection.
The components and auxiliary equipment are designed in such a way as to ensure the safe replacement of LV HRC fuse systems or isolation of systems.
LV HRC fuse links are available in the sizes 000, 00, 0, 1, 2, 3, 4 and 4a.
LV HRC fuse links are available in the following operational classes:
- gG for cable and line protection
- aM for short-circuit protection of switching devices in motor circuits
- gR or aR for protection of power semiconductors
- gS: The new gS operational class combines cable and line protection with semiconductor protection.
LV HRC fuse links of size 000 can also be used in LV HRC fuse bases, LV HRC fuse switch disconnectors, LV HRC fuse strips as well as in LV HRC in-line fuse switch disconnectors of size 00.
The fuse links 300 A, 355 A and 425 A comply with the standard but do not have the VDE mark.

Benefits
Picture left: Tripped,
Picture right: Not tripped
- LV HRC fuse links with combination alarm signal the tripping of a fuse by a clear color change from red to white. This enables fast identification and replacement of the tripped fuse links. This increases plant availability
- The insulated grip lugs made of metal are integrated in the top and bottom covers of the fuse link in molded plastic and provide greater safety during replacement. The mark shown below indicates that the grip lugs are insulated.

- In the standard series with front indicator, the front-mounted red indicator signals the tripping of a fuse
- LV HRC fuse links are always equipped with silver-plated contact pins. This means that they are non-corroding and have less contact resistance. This ensures the long-term operational safety of the plant.
