Abstract

A system for protecting an electrical circuit comprises at least: an electrical protection switching device comprising: neutral and live input terminals for electrical connection to a neutral line and a live line provided by a supply of the electrical circuit, neutral and live output terminals for providing the live and neutral lines to a load of the electrical circuit, a movable contact associated with the at least live line which can be opened for disconnecting the load from the supply, an electrically controlled actuator arranged to open said movable contacts, and a fault detector for causing the actuator to open said movable contacts upon detection of a residual fault current between the live and neutral lines; and a series detector electrically coupled to the live and neutral lines for detecting a fault current between the neutral and live lines. In case of detecting a fault current, the series detector is configured to close a contact for realizing a current imbalance path generating a differential current between the live and neutral lines to simulate a residual fault current detectable by fault detector of the electrical protection switching device, the current imbalance path being connected to the neutral input terminal and to the live output terminal of the electrical protections switching device. <Figure 1>
