Abstract

According to the invention, the retaining force of a permanent magnet, which forms part of the tripping magnet (11) in a circuit breaker forming part of a power switch (2) in a power supply circuit, is monitored, whereby the release coil of the tripping magnet (11) is energised with a pulse of current before a predicted response, whose duration is shorter than that duration necessary for the desired response.
