THE PRESENT INVENTION RELATES TO A MULTIPOLAR ELECTROMAGNETIC SWITCHING MODULE THAT IS CONNECTED BY LINE CONNECTIONS (U, T2, T3) TO A MAIN MULTIPOLAR ELECTROMAGNETIC SWITCHING DEVICE (AP) AND BY LOAD CONNECTIONS (U, V, WE U’, V’, W’) TO AT LEAST ONE MOTOR AND HAVING BETWEEN SAID CONNECTIONS SEVERAL POWER CURRENT LINES (C1, C2, C3) FITTED WITH SWITCHING POLES THE CONTAÊ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’(FIG 1) |
