<p>The device (1) has a power-limiting circuit and a current-limiting circuit, which are active between a voltage source (3) and a load circuit connector (4). An intrinsically safe load circuit (2) is connected to the connector. A resistor (6) having a resistance value limits a short circuit current to a specific current. The power-limiting circuit and the current-limiting circuit are connected in series one behind the other. The current-limiting circuit is connected to the connector. A current-measuring unit measures a load current taken from the connector.</p> |
