LV HRC fuses are used for installation systems in non-residential, commercial and industrial buildings, as well as in the switchboards of power supply companies. They therefore protect essential building parts and installations. LV HRC fuses are fuse systems designed for operation by skilled personnel. 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 fuses 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 the short-circuit protection of switching devices in motor circuits gR or aR for the protection of power semiconductors gS: The new gS operational class combines cable and line protection with semiconductor protection.
HRC fuses (DIN) 3NA • High Breaking capacity of 120kA • Dual indication for fault detection • ISI marked • Highly compact: upto 100A in size 000 • Utilization Category gG • Rated breaking capacity: 120kA (AC), 25kA (DC)
