When out of electricity distribution system electric current consumption is switched over, by means of MTC devices, from I (high-priced) to II (low-priced) tariff then the indicator (3) turns on a light indicator of the low-priced tariff at the distribution board of electric installation at electric current consumer (provided that the electric installation is carried out according to regulations). The same voltage switches off relays (or circuit breaker) (1) that over the working contact switches off or shortly connects the automatic overload device (2) i.e. turns it off the electric circuit of wirenet, so that the electric consumers are now fed by electricity from the limiter (2) but according to (low-priced) tariff. The invention is solved in two variations of embodiment, where magnetic electric magnetic components and /or semi-conductive components are in use. In this, simple and proportionally low-priced, way electric energy can be saved during I tariff, but the ratio of electric energy onsumption during II tariff can be increased. The fact is of importance for electric distribution system, and particularly for consumers of electric current, with regard to a kWh price, a red tariff and an engaged power. |
