ABSTRACT:
A circuit configuration for protecting the on-board electrical system of a motor vehicle includes an input connected to a voltage source, an output connected to a load and a ground connection being common to both the input and the output. A current stabilizer regulates an output current. A switch controls the current stabilizer as a function of the output current. An overload switch carries an overload current from the input through the current limiter to the output upon the appearance of an overload at the output, and carries a short-circuit current from the output through the excess voltage switch to ground upon a short circuit at the output to an excess voltage.
