Fuses - NH

CONSTITUENT PARTS FOR NH FUSES:
The body of the fuse-link is made of quality steatite which is highly resistant against temperature overloads. In the inner part of the steatite body there is a copper melting element which is welded on a specially shaped inner part of the contact knife by spot welding. By careful shaping of this part during assembly the melting element is placed exactly into the middle of the inner place. The remaining inside place of the ceramic body is filled up with precisely determined granulation and chemical structure quartz sand. All contact knives are additionally protected with a layer of silver or nickel. On the basis of cyclic tests we have proven that the fusing characteristics are very stable and the tolerance on the current axis can be up to ± 10%.
