Abstract
A method for operating an electronic circuit arrangement is provided for electrical current limiting in a potentially explosive area, which comprises at least one electrical consumer which is supplied with electrical energy via an electrical supply line from an electrical voltage source, typically from a rechargeable battery which provides an electrical supply voltage, according to which at least one of at least two semiconductor switches present in the electrical supply line is switched into an open state so that the electrical supply line is interrupted when the total electrical voltage present at the semiconductor switches exceeds a predefined voltage threshold value, and according to which the at least one semiconductor switch is switched from the open into the closed state again when an external electrical voltage is applied to the electrical consumer.
