When using distribution box in winter, attention should be paid to the selection of AC contactor

The hot summer has passed, and the cold winter has arrived, and the peak of daily power consumption has arrived as scheduled. The distribution box, as a power consumption device, will play a greater role in this season than in communication. I believe those who have learned about the stainless steel distribution box should know that the internal components of the distribution box are composed of some low-voltage electrical appliances. When we choose it, we need to pay attention to its internal components, and pay more attention to the selection of AC contactor of distribution box. Today, Xiaobian will talk to you about the importance of selecting AC contactors for distribution boxes.

Since AC contactors with the same capacity are installed for different outgoing circuits, and the imbalance of three-phase load is not considered, the current level of some outgoing contactors is not increased by one current level based on the normal selection model, which is easy to cause the AC contactor to burn out during operation in dry season in winter.

In order to avoid such a situation, the AC contactor of the distribution box shall be energy-saving AC contactor (similar to cj20si type), and pay attention to the connection between the coil voltage of the AC contactor and the corresponding terminal selected as the current action protector, and pay attention to the correct load matching. Therefore, its selection is very important. It needs to meet the standard requirements for the use of distribution box. Don't ignore it!
