However, this energy-saving operation is not generally applicable. If, for example, a contactor must automatically fall back to the switched-off state in the event of a mains voltage failure, mechanical latching could not be used until now. The ESR 1 generates a switch-on pulse and stores energy. Thus, it can not only bring a contactor into mechanical latching, but also reliably release it again automatically when the mains voltage fails, dimensions: 18x55mm, 230V AC , EAN: 4046929601177.
