To create a safe and high-quality wiring, it is very important to choose the right devices and equipment to help ensure this. For electrical wiring, both in the house and in large industries, you can not do without a modular contactor. What modular contactor? This is a special device that allows bundles of different types of current. Please note that switching processes are required in almost any system. That is why these devices are almost always required. Consider what features differ modular contactors, what are the varieties of devices for work.
The main types
There are several classifications of this equipment, so modular contactors must be carefully selected based on their purpose and scope. So you can choose several main types:
- According to the type of operation, the contactors can be mechanical and electromagnetic. The first option is already out of fashion, since its reliability is several times lower than that of the electromagnetic one. In addition to high quality, electromagnetic modular contactors also feature a low number of vibrations during operation, and also extraneous vibrations do not spoil the work. Also, a modular electromagnetic contactor practically does not create noise during operation, which allows you to make comfortable living conditions in everyday life;
- The number of phases in the contactor can be one or two. You need to choose depending on the electrical wiring, as well as the equipment that is used in the house. The number of poles may also vary. Pay particular attention to the number of contacts. Usually there is only the main quantity, but recently more and more often additional ones are installed for the reliability and high-quality operation of switching equipment;
- Pay attention also to the method of breaking the network, which is the contactor. There are two main options: single and double. The first type is most often used for complex installations and electrical systems. This is due to the fact that the extinction of the arc in this case is very high quality and efficient. Often used in construction (railway) and during the creation of modern induction furnaces. The dual contactor is expensive and is used only in complex types of work.
