Abstract:
1. A module for measuring a current flowing in a conductor of a low-voltage distribution board, the module comprising: a current sensor configured to detect the current; a microprocessor circuit configured to process an output signal emitted by the current sensor; and a module housing which accommodates the current sensor and the microprocessor circuit, wherein the module housing includes an opening for passing the current conductor therethrough, an interface having two current connections, which are connected to the microprocessor circuit and are connectable to an external voltage source that provides up to 24V direct current, and a connecting element for releasably fastening the module in the low-voltage distribution board, and wherein the opening extends from a side of the module housing bearing the interface, through the current measuring module, to an opposite side of the module housing, and the module is configured to be DC-isolated from the current conductor after the module has been installed in the low-voltage distribution board.
