2A1909-26 is an accessory device often used with mechanical and electrical equipment. This device is a low voltage and current limit device, with a wide range of application in all kinds of industrial fields. It is mainly used for control automation and other related applications.

2A1909-26 is an important component for ensuring the safe operation of industrial automation equipment, as it can protect other components from damage or wear caused by excessive current. It can limit the current to a preset value, reduce the risk of damaging the internal device. As a result, it can greatly reduce the maintenance cost of the device and ensure its smooth operation.

2A1909-26 Working Principle

The working principle of 2A1909-26 is based on the principle of overload protection. Its overload protection function is enabled by a bimetallic copper-aluminum strip with a thermal coefficient of expansion. When the load is heavier than the current rated value, the copper-aluminum strip heats up gradually, activates a metal contact mechanism and separate the circuit, which then stops the current flow. Conversely, when the load decreases, the copper-aluminum strip cools down and restores the contact, allowing the circuit to resume. The overload protection limit can be adjusted by changing the shape of the copper-aluminum strip.

2A1909-26 Application Fields

2A1909-26 is widely used in industrial automation, and can provide overload protection for motors, transformers, reactors and other electrical components. It can also be used in industrial power storage, control cabinets and other places where current protection is required. In addition, the device can also be used in other fields such as electromagnetic enterprises, wire processing and instrumentation construction.

In addition to the application in industrial automation, 2A1909-26 can also be used in everyday life. It is often used to protect electronic appliances such as computers, TVs, refrigerators, and other electronic products, prevent overload, as well as provide safety protection in case of accidental overload.

Conclusion

2A1909-26 is an accessory device with a wide range of applications in all kinds of industrial fields. It can protect the industrial automation equipment from damage or wear caused by over current, thereby reducing the maintenance cost and improving the work efficiency. In addition, it can also be used in everyday life to provide safety protection for electronic appliances such as computers, refrigerators and TVs.
