Low voltage NH knife-blade fuse-links

Transcription

1 Low voltage NH knife-blade fuse-links NV KOMBI advantages ETI is introducing a new generation of low-voltage fuse-links from size NV00C up to NV3 with new, dual indication of fuse-link operation, called KOMBI. The indicator is easily visible on the top and centre of the fuse-link, whether it is situated in a standard fuse base or vertical fuse rail or in fuse-switch disconnector. The most important advantages of KOMBI fuse-links: High breaking capacity, ka (00 V gg - except NV00C and NV00CI, and 500 V gg) and 0 ka (00 V gg NV00C and NV00CI, 90 V gg, 00 V gtr, 00 V gf and 90 V am) voltages: 00 V a.c., 500 V a.c., 90 V a.c. and 00 V a.c. Two versions of covers: aluminium, when the removal tag is under voltage and plastic, when insulated metal removal tag is incorporated into the plastic cover VDE certificates and CCA/CB test reports General about fuse-links Their dimensions correspond with DIN 30, other technical characteristics correspond with the requirements of the following standards: voltage 00V/500V/ IEC 09-1:005 / EN 09-1:1998+A1:005 IEC 09-:198+Corr.1: 90V/gG: 199+A11995+A:001 / EN 09-:1995+A1:1998+A:00 IEC 09--1:00 / HD 09--1:005 voltage 90V/aM: VDE voltage 00V/gF: PN-IEC 09- voltage 00V/gTr: VDE Short description of constituent parts for NV fuse-links 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 we achieved that 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 on special order of nickel. On the base of cyclic tests we have proved that the fusing characteristics are very stable and the tolerance on the axis can be up to ± %.

9 Fuse-link am Breaking capacity voltage -150 A 0 ka / ka 500V, 90 V Fuse-links with am characteristics are intended for protection of switchgears and controlgears as well as motors in motor drives where gg characteristics do not comply with all requirements of succesful protection of these devices. They are made in all standard NV sizes from 00 to a for all standard rated s and for voltages to 90 V. Their main duty is to enable a full usage of switchgears and controlgears in the region of starting s and to prevent sparking or destruction of protective contacts in case of short-circuit s. It should be noted that these fuse-links are intended only for protection in the limited region (in the region of short-circuit s). fuse-link am NV 00 C kombi NV 00 kombi NV 0 NV 1 kombi Code No. ~ 90 V, 0 ka NV C kombi NV kombi NV3 kombi ** ** ** ** ** ** ** ** * ** * ** ** ** ** ** ** ** ** ** ** ** Weight and Packaging the same as for gg fuse-links. *500V, ka ** NOT in KOMBI version NVa 58 Technical data on page 58
