| 摘要 |
<p>The invention concerns a reverse current relay comprising a relay magnet and a protective device each capable of acting through a multipolar member on mobile contacts in response respectively to a deliberate command or an electric fault detection. A control mechanism (40) for the contacts is provided with a electromagnetic tripping element (41). The protective device (30), preferably interchangeable, is connected to the relay magnet (20) by a control linkage (33B) and to the control mechanism (40) by a triggering linkage (33A), so as to deliver, in the event of a fault, a triggering signal on the triggering linkage. The relay magnet (20) is powered with direct current and the protective device (30) adjusts its voltage supply.</p> |
