FIELD: electricity. ^ SUBSTANCE: invention refers to overvoltage protection with state alarm which includes at least one linear resistance element with shut-down device conjugated to overvoltage protection state alarm device. Overvoltage protection includes the only shut-down device which is equipped with devices for at least two-step movement of actuating element depending on the temperature of non-linear resistance element; at that, actuating element is conjugated to alarm device of stepped movement of actuating element. ^ EFFECT: simplifying and reducing the costs for the device production. ^ 6 cl, 25 dwg |
