Medium-voltage fuse-link ETI VV TD3

ceramicfor electric motorsfor transformers

Introducing a new line of medium-voltage fuses VV with low minimum breaking currents, high breaking capacity up to 63 kA, two types of striker pins: 50N and 80 N (with integrated temperature dependent limiter) and reliable sealing system against humidity irruption. VV fuses are used to protect distribution transformers, high-voltage motors, high-voltage capacitors, voltage transformers... KEMA type test reports Reliable sealing system against humidity irruption High endurance ceramic tube Low temperature rise because oflow power dissipation Low minimum breaking currents Low switching voltages High breaking capacity 63 kA Silver melting element Galvanically protected contact caps made of electrolytic copper can be nickel (Ni), tin (Sn) or silver (Ag) plated Striker system: a temperature sensitive element, which does not react to short time overloads, only to inadmissible values of temperatures. Convenient for the protection of the fuse-links, installed in enclosures or SF6 switchgears Rigid striker pin Various striker variants (50N, 80N, without striker, thermo, non-thermo...) Easier mounting because of improved contact cap The suitability of the new series of VV fuse-links has been confirmed by certification at the KEMA Labs Institute in Prague, which is part of the CESI Group. We obtained a new KEMA / CESI certificate for 12- and 24-kilovolt fuse-links for the I1, I2 and I3 tripping capacity tests.
