European NH Knife-Blade Fuse System General > p (sym.r.m.s.),depending on the moment of energizeing and the value of the d. c. component of that short circuit.High short circuit currents do not rise up to theirpeak value when SIBA LV-fuse-links of a correspon- ding rated current are used. The current limiting effect starts at melting times of less than 5 m. s.The current limiting diagram shows the behaviour ofthe prospective short circuit current I Users demands for maximum service reliability inlow voltage networks, coupled with effective and economic operation, places considerable quality...

European NH Knife-Blade Fuse System The discrimination between two fuse links of diffe-rent current ratings can only be determined when considering the service voltage. The degree of discri- mination in radially operated systems of 1:1.6, as well as the use of fuse links of the same rated cur- rent in meshed networks, is only applicable at servi-ce voltages 1.1 x U gTr > N 3. SIBA LV-fuse-links of duty gTr are with a specific curve adapted to the load charcterisitc of the trans- former. Therefore better utilization of the overload capacity of transformers is achieved. SIBA transfor-...
