Traditional communication contactor long life and long reliability?
Compared with the traditional contactor, permanent magnet AC contactor in closing, in addition to the same electromagnetic force, but also has the role of permanent magnetic force,
Contact ablation is mainly caused by the opening, closing the arc caused by the closing.
especially the voltage, current, magnetic gap increases easily lead to heat and the coil burned, and permanent magnetic contact device is not possible to burn the coil.
Contactor life and reliability are primarily determined by coil and contact life. Traditional AC contactor because of its work when the coil and the core will be hot,
