Abstract
This electromagnetic contactor comprises a set of controlled switches (C1, C2, C3), at least one electromagnetic field generator (L; L1, L2), for example a coil, associated with an adjustable core (P) controlling the state of the controlled switches and a unit (UC) controlling the power supply of the electromagnetic field generator. It comprises means for detecting the position of the adjustable core to detect the state of the controlled switches.
Claims9
An electromagnetic contactor, comprising a set of controlled switches, at least one electromagnetic field generator, for example a coil, associated with an adjustable core (P) controlling the state of the controlled switches, a unit controlling the power supply of the electromagnetic field generator and means for detecting the position of the adjustable core to detect the state of the controlled switches wherein it comprises storage means in which are stored impedance values, notably values of the resistance of the generator, as a function of the temperature of the generator, said impedance value of the generator being extracted from the storage means.
