It is worth correcting that the load that the contactor can bear has little to do with the coil voltage; Because the coil voltage of the contactor is not the main circuit voltage, it is completely two concepts. The function of contactor is to control low voltage, high voltage, small loop and large loop. The coil voltage of the contactor only makes the contactor work, which has nothing to do with the main circuit voltage; The current and voltage of the main circuit act on the main contact of the contactor.
Generally speaking, the maximum withstand voltage of ordinary AC contactor is 690V, but DC contactor is constant voltage and will not fluctuate, so there is no maximum withstand voltage, only the rated working voltage.
