Abstract
For a preset period following application of a closing order, the semi-conductor of the static power switch, supplied with DC voltage, is controlled by a regulating circuit so as to operate as a current generator limiting the current to a value much lower than its rated value. A fuse acts as measuring shunt. The switch can comprise a circuit breaker function. In this case, the fault detection circuit measures the voltage at the terminals of the semi-conductor and supplies an opening signal when this voltage exceeds a preset threshold.
