| 摘要 |
<p>The invention relates to the overvoltage protection with status signalling, which contains at least one non-linear resistance element with cut-off device coupled with status signalling device of overvoltage protection. The overvoltage protection contains a single cut-off device which is equipped with means for at least two-stage shift of an actuator depending on temperature of non-linear resistance element, while the actuator is coupled with signalling device of step shift of the actuator.</p> |
