Resistance module for contactor

摘要

Two modules are used for each phase of the contactor, each module being connected between one of the phases of the latter and the corresponding phase of the auxiliary contact block (16) in order to protect the contactor against current peaks when activated. The module includes winding support means (2) with a winding of resistance wire (1) thereon. One of the ends (4) of the winding support means (2) constitutes the means of connection to one of the phases of the contactor. The module includes means for coupling (13, 12) the end (6) of the resistance wire (1) to the end (7) of a flexible cable (8), the other free end of which is connected to the corresponding phase of the auxiliary contact block (16). In addition, it has housing means (9 and 10) for retaining and protecting of the foregoing components. This structure has a reduced volume and prevents mixing different phases during installation. <IMAGE>
