At present, there are many kinds of DC contactors in the market, with different specifications performances. In addition, users should consider many aspects when purchasing, only in terms of performance price, but also in terms of type load.

Brief introduction of DC contactor

First of all, the type of DC contactor, the need to consider is to buy light load heavy load general load. These three different types of DC contactor bring different performance efficiency.

The second is the operating frequency of DC contactor. Generally, when purchasing DC contactor, we will consider the number of times that DC contactor turns on off every hour. If the on-off current is large the frequency is high, if the rated current of purchased DC contactor is enough, it is likely to cause relay overheating even contact burning out, which only brings inconvenience to work, but also may lead to certain fire hazards.

When users choose buy DC contactor, they will generally decide the model according to the current type load weight required. In addition, some users who are more strict with the product will also consider the contact in the DC contactor, because the current needs to be calculated based on certain data. However, if the operation of the selected DC contactor is too complex, it will be reduced by one level when selecting the contact.

Can DC contactor be used in AC circuit

In addition, in the view of some users, the frequency of power on power off that the DC contactor can withstand in a certain period of time is a matter of great concern to them. The main reason is that the manufacturers of high frequency mechanical operation with user data need to turn off power on the mechanical equipment for many times in a short time. If the bearing capacity of DC contactor is enough, the whole circuit may be burnt out. Therefore, the general DC contactor manufacturers will recommend this kind of customers to choose DC contactor which is bigger than the psychological goal.
