What is a DC contactor? So what is a DC contactor? The following 400A DC Contactor manufacturers will begin to answer this question.
The manufacturer of 400A DC Contactor tells you that the DC contactor design scheme selects a standardized modular design, and uses relatively few and excellent spare parts for the assembly of AC contactors. Humanized product customization can also be carried out according to the different requirements of customers, and resources can be reasonably saved. The DC contactor carries out high-voltage disconnection according to the contacts, and also applies transverse electromagnetic field and magnetic blowing to carry out the opening and closing of the working voltage. Open change. The manufacturer of 400A DC Contactor tells you that the product is widely used in industrial production. The power source of the power circuit is reasonably manipulated, and the internal coil is used to create an electromagnetic field under the effect of the current flow, which promotes the product development and manufacturing of new high-tech products.

The manufacturer of 400A DC Contactor tells you the design of the coil in the DC contactor. After the switching power supply is turned on, the current will be converted into electromagnetic field according to the coil. Let the static iron core contain the current capacity magnet adsorption force, push the iron core, and perform the contact function. The manufacturer of 400A DC Contactor tells you that if the contacts are often turned off, showing a broken situation, if it is often used, the contacts are closed and the two are connected to each other. After we cut off the power, the magnetic attraction force of the coil caused by the effect of the current flow will disappear, and the open and closed contacts may be disconnected.
1. Choose the type of DC contactor The type of DC contactor should be selected according to the type of load current and the lightness and heaviness of the load, that is, to communicate with AC load or DC load, whether it is light load, general load or heavy load.
2. The rated voltage of the main contact of the DC contactor The rated voltage of the main contact of the DC contactor can be calculated according to the working experience formula IN main contact ≥ PN motor/(1~1.4) UN motor If the motor operated by the DC contactor is running, The braking system is often turned over. The 400A DC Contactor manufacturer tells you that the rated voltage of the main contact of the AC contactor is generally reduced by one level.
3. The rated voltage of the main contact The working voltage marked on the factory nameplate of the AC contactor refers to the rated voltage that the main contact can bear, not the working voltage that attracts the coil. The rated voltage of the main contact of the AC contactor should be Not less than the rated voltage of the load.
4. Selection of actual operating frequency The actual operating frequency refers to the frequency of the AC contactor conduction per hour. The manufacturer of 400A DC Contactor tells you that when the conduction current is large and the conduction frequency is too high, it will cause serious over-temperature of the contacts, and even arc welding. If the actual operating frequency exceeds the required mark value, a DC contactor with a rated voltage one level higher should be used.
5. The manufacturer of 400A DC Contactor tells you the selection of the rated voltage of the coil. The rated voltage of the coil is not necessarily the same as the rated voltage of the main contact. When the route is simple and there are few household appliances, the working voltage of 220V or 380V can be used immediately, if the route is complicated , The application of household appliances for more than 5h, you can use 24V, 48V or 110V working voltage (in 1964, the international requirement is 36V, 110V, or 127V) coils.
