Elektrischer Überstromauslöser für einen Niederspannungs-Leistungsschalter |
摘要 |
The overall characteristic curve for an overload trip should fall monotonically, which isn't always the case for certain choices of set values. According to the invention, the characteristic curve of an overload trip in the overload region (I), for a section of the curve situated before the short-delayed short-circuit region (II), may be set with the delay time (tsdi), which is independent of current and dependent on the short delay time (tsd) and which is at least as big as the short delay time (tsd). The above is particularly advantageous in the case of current measurement by means of Rogowski coils.
