Abstract: An electrical switching device for fault-current, overcurrent and short-circuit current protection, has a contact point in a current path and a switching mechanism for permanently opening the contact point. The switching device further has a configuration for detecting the fault current, the overcurrent and the short-circuit current, and contains two permanent magnets and a core.

Abstract: The invention relates to a method for determining a value of a current using a current transformer that operates in the core saturation region. A peak value detector determines a peak value of one half-cycle of the secondary current. The peak value is stored in a storage element for further processing. A comparator detects that the peak value has been reached. After this, the comparator supplies a switching signal to a signal processing unit, and this signal starts the signal processing unit. The signal processing unit receives the peak value that was stored in the storage element and provides this value for further processing. A RESET pulse is then transmitted to a switching apparatus to discharge the storage element and thus allow the detection of the next peak value.
