Purpose: In European Union countries by January 1st 2007 at the latest, all articles and products containing cadmium will either have to be withdrawn from sale or an appropriate substitute for this heavy metal will have to be found. Design/methodology/approach: The present technology of production of fuses in Slovenian firm ETI Elektroelement and the action thereof are adapted to the existing ecologically harmful alloy of tin and cadmium SnCd20, which ought to be replaced by one or more ecologically safe alloys with technological and application properties as similar as possible to the existing ones. Findings: In the frame of our common investigation work we have found that the stated problems can be successfully solved by the low melting alloy of tin, bismuth and antimony named ETI-Sn-Bi-Sb. Research limitations/implications: Alloy is ecologically safe, and by its technical and physical properties corresponds to the requirements of the use for fusible elements of low voltage fuses. Practical implications: Practical implications of this work is in introduction of new ecologically safe material for fusible elements, without cadmium in the existing technology of low voltage fuses. Originality/value: Originality and high value of our engineering work is confirmed by two Slovenian national patents and European Union patent for the ecologically safe low melting alloy ETI-Sn-Bi-Sb, which received Slovenian firm ETI Elektroelement and authors of this paper.
