I will say one minor drawback is that the contactor makes an obvious buzzing sound when first connecting but the sound tapers to pretty quiet. When you checked the voltage, did you do so with the coils attempting to energize? Another common issue is that when the contactor closes and starts the motor, the added motor starting current causes a voltage drop, which chatters the contactor. If you have a loose neutral somewhere, this could make it worse. this can often cause chattering of a contactor. Refine Your Search. Product benefits.
