A/S EF "JAUDA" produces NH type fuses dimensions from 000 to 4a under strict supervision of quality control team, the fuses are produced under M.Schneider-Annaberg GmbH license and fully conforms European Norms EN 60 269-2-1, VDE 0680/4 and DIN 43620/4. Insulating cases are made of temperature oscillation resistant materials – steatite or corderite. The standard model has moving insert made of copper. The contact knives are made of copper covered with silver. Functional constructions of fuses witch a large range of dimensions (DIN 43620) and current types are: Dimensions | Current | 000 | 2A ÷ 100A | 1c | 16A ÷ 160A | 1 | 200A ÷ 250A | 2c | 25A ÷ 250A | 2 | 300 ÷ 400A | 3 | 100 ÷ 630A | 4a | 400 ÷ 1600A |
Possible rated current /A:
2, 4, 6, 8, 10, 12, 16, 20, 25, 32, 35, 40, 50, 63, 80, 100, 125, 160, 200, 224, 250, 300, 315, 355, 400, 425, 500, 630, 710, 800, 1000, 1250, 1600. The fuse time current characteristics conform to European Norms EN 60 269 (IEC 269) and fuses are available in the following classes:
gL/gG – for cable and line protection
aM – for protection of motor circuits
gTr – for transformer protection
gR – semi conductor global protection, aR – semiconductor local protection
gB – for mining applications. The fuses have two types of indicators (strikers) – red button, which dashes out in case the moving element burns out, or signal flag that works in the similar way. It helps to identify the damage place, thus the time is saved. |  |
