The invention relates to a voltage protector for detecting shunts and overvoltages in the electrical grid, implemented as an electromechanical control system comprising a base circuit with an electrical current input connection including an earth and an external point connected to the shell or accessible surfaces of the device by means of an earth cable, and having at least one outlet for connecting to the functional element of the device and a modular operating system connected to the base circuit and including a power source, a sensor for detecting shunts or overvoltages and a switch or relay. The base circuit includes a safety element for disconnection from the power and can be connected to the safety element by means of a manual push button or remotely. The device includes a neutral point detector connected to a light-emitting diode. |
