Arcing between the contacts as galvanic corrosion caused by the amount of contact may be different

AC contactor control coil voltage alternating signal is therefore in a different phase AC contactor closing down its closing dynamics of the process are different. In the closing phase angle under different closing, contact bounce duration, velocity  electric transformer  of the armature and the collision energy is different turn-on circuit current maximum occurs is different, because arcing between the contacts caused by touch head electric corrosion amount may vary. Contacts  Voltage stabilizer  to  air circuit breaker the wear of the contacts, resulting in electrical life shortened. Therefore, when closing the contactor contact bounce is that important performance parameters. This article based on the operation principle of the contactor, the contactor selected on the basis of the analysis phase excitation.
