(Summary description)When selecting a china 200A DC Contactor, it is necessary to first select its type, and then select the rated parameters of the DC contactor. According to well-known contactor manufacturers, it is generally recommended to choose a 200A DC Contactor with a relatively low voltage to reduce its insulation requirements, which can also increase the safety of use objectively.

When selecting a china 200A DC Contactor, it is necessary to first select its type, and then select the rated parameters of the DC contactor. According to well-known contactor manufacturers, it is generally recommended to choose a 200A DC Contactor with a relatively low voltage to reduce its insulation requirements, which can also increase the safety of use objectively.

For example, if the circuit to be controlled has no complicated steps and the amount of electrical appliances used is small, then a china 200A DC Contactor with conventional voltage can be directly selected; if the circuit is complex and the number of electrical appliances is large, another voltage coil needs to be selected. thus ensuring safety. If the operating frequency of the motor is relatively low, such as air conditioners and compressors, the rated current of the china 200A DC Contactor is slightly larger than the rated current of the load, so that the stability and safety will be doubled in the later work. For heavy machinery such as the main motor of machine tools, the rated current of the selected DC contactor is slightly larger than that of the motor.
If the china 200A DC Contactor is used to control the transformer, the factors of inrush current need to be considered as appropriate when selecting. For example, taking an electric welding machine as an example, china 200A DC Contactor products can generally be selected according to twice the rated current of the transformer.
