2AS2-5

2AS2-5 is a type of electric contactor, which is used to control the working of an electric motor. It is designed to be able to start and stop electric motors in a variety of industrial applications. It was introduced by Siemens in the mid 70s and is still widely used today because of its reliability and its ease of installation. This article will discuss the application fields and the working principle of 2AS2-5 electric contactors.

Typical Applications of 2AS2-5 Electric Contactors

2AS2-5 electric contactors are mainly used to control the on and off operation of industrial motors. They are usually used in applications where the motor must start abruptly or be stopped suddenly. Some of the most common applications where they are being used include cranes, elevators, pumps, air compressors, electric tools, conveyors, and hvac systems. In each of these applications, the contactor is able to start the electric motor and stop it safely when necessary.

Working Principle of 2AS2-5 Electric Contactors

The working principle of 2AS2-5 electric contactors is relatively simple. The contactor consists of an electromagnet and several contact points. When the contactor is turned on, the electromagnet is energized, causing the contact points to open. This causes the electric current to be cut off from the motor, stopping the motor from running. When the contactor is turned off, the electromagnet is de-energized, causing the contact points to close. This allows electric current to flow through the motor, allowing it to start running.

Advantages of Using 2AS2-5 Electric Contactors

2AS2-5 electric contactors have several advantages over other types of electric contactors. Firstly, they are very versatile and can be used in a variety of applications. Secondly, they are very reliable and can operate smoothly for long periods of time. Lastly, they are relatively easy to install and are available in a wide range of sizes and configurations. These advantages make them ideal for use in many different applications.

Conclusion

2AS2-5 electric contactors are a reliable and versatile solution for controlling the electric motors in various industrial applications. They are easy to install and have been proven to provide reliable operation for many years. In addition, their design makes them ideal for use in a wide range of applications, from cranes to pumps to HVAC systems.
