Abstract
A power cut-off device comprises first and second electronic switching devices (FETs T2 and T1) which are cross-coupled so that when one switching device is on the other is off and vice versa, and a load (11) to be protected is connectable in series with the first switching device (FET T2). If the current through the first switching device (FET T2) exceeds a certain value, caused for example by a short circuit at the load, the second switching device (FET T1) is turned on to turn the first switching device off.
