SIBA fuses | 800 V AC

The new series of SIBA NH fuses with operating class: gRL (gS) has been developed for the line protection of the new String Inverters.

Due to the use of special geometries of melting elements, in comparison to the conventional line protection fuses of operating class: gG, a considerably faster operation at short circuits and thus optimum protection of the inverters has been realized. In the space-saving NH standard designs, the fuse links achieve a maximum breaking capacity of 120 kA with a test voltage of 800 V.

The power losses of series NH 00, NH 1 and NH 3 have been designed for the respective maximum power acceptance
of the corresponding NH fuse bases and fuse switches.
