3 Specification Assembly Fuse body (1) The fuse body consist of ceramic material of high quality in brown, environmentally friendly colour. Contact caps (2) The con tact caps con sist of high co nduc ti ve, elec tro ly tic cop per and are eit her ni ckel or sil ver pla ted. Ex cel lent tight ness and re sul ting high re sis tan ce to ageing is achie ved due to a spe ci al me thod of rol ling by pres sing the con tact caps into the groo ve of the fuse bo dy's tube. Fuse element In si de the fuse body sil ver fuse ele ments con nec ted in par al lel (4) are wound around a star core (3). The se fuse elements are ex act ly adap ted to gua ran tee their cor rect functi on in case of short cir cuit cur - rents. The fuse ele ments are wel ded on to both con tact caps. Quartz sand fil ling The fuse body is fil led with quartz sand with pre ci se gra nu la ti on. Op ti mum arc ex tingu is hing as well as high interrupting capacity is guaranteed by the sand's granulation and composition. Striker (5) see page 4 sta tus sub ject to al ter ati on

The striker mechanism (5) provides a visual indication of the operation of the fuse link. In con nec ti on with an in di ca ting de vi ce at the high vol ta ge dis con nec tor the stri ker can also be used as a mechanical indicator. dimensions see page 11 striker Application The ran ge of ap pli ca tions for high vol ta ge fuse links are the pro tec ti on of high vol ta ge po wer li nes, trans for mers, mo tors, con den sa tors as well as switch bo ards and dis tri bu ti on units for pub lic uti li ties and the in du stry.
