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 sizeВ 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 sizeВ 00.

The fuse links 300В A, 355В A and 425В A comply with the standard but do not have the VDE mark.
