Abstract::

The importance of use of fuses as protection elements in DC circuits has increased recently. This article deals with some theoretical points and explanations of basic notions in DC circuits. Further on, some of the most common applications are described, where conventional shortcircuit protection is not sufficient enough and special requirements of designers or customers are necessary. Besides world trends in the field, some ETI new products, developed for DC circuits are presented.
