<p>A moving contact (2) is directly driven by a blast disk (5) into OFF position. To restrict current effect, there is arranged an electronic circuit with limiting capacitor (20), switching thyristor (18), capacitor (15), diode (21) and a measuring member (22) of the current. No transient process occurs in this circuit, which during millisecond order units secures, in connection with fast mechanics, a fault current interruption.</p> |
