<p>A device for breaking the supply of current to a mains-connected electronic equipment which has two different normal alternative current consumption levels, because the equipment current consumption deviates from one of these current consumption levels. The device includes a current breaker which is connected in series with the equipment current supply line. The device includes a window discriminator for each power level, and the discriminators are coupled to control means which function to cause the current breaker to isolate the supply of current to the equipment when the equipment current consumption does not lie within any of the windows.</p> |
