Abstract (en)
[origin: DE10051161C1] The contact wear reduction method has the switching command (ES) used for electromagnetic operation of the main contacts (K1-K3) of the switching device (1) delayed, for initiating switching at a phase angle of the control voltage (Us) for the magnetic system (4) which is compared with the switching command angle exhibiting the maximum contact wear by a phase comparator. The actual contact wear of each main contact is determined via a time interval measurement for the contact separation switching process. An Independent claim for a wear reduction device for a switching device is also included.
