Abstract

In order to adjust retaining magnet trip devices, the field strength of the permanent magnet is adjusted to a nominal value. For this purpose, it is initially magnetised and subsequently demagnetised in a monitored manner. According to the invention, magnetisation is carried out by applying a pulse in the same magnetic field direction and demagnetisation is carried out by applying a pulse of decreasing amplitude from an alternating magnetic field. For use in fault-current circuit breakers, the retaining magnet is adjusted for a plurality of fault-current types. <IMAGE>
