3DU2L is a type of circuit breaker that is able to provide protection against short circuits, overloads and misoperations of electrical control circuits. It is often used in the field of industrial control systems, power conversion and other fields. 3DU2L circuit breakers are reliable and flexible, with a wide range of applications.

In terms of structure, 3DU2L circuit breakers are composed of two parts, a main switch and an auxiliary switch. The main switch is used to disconnect the electrical circuit and is operated by a lever or button. The auxiliary switch is used to transmit the connected signal to various control circuits and can be operated manually or automatically. The two switches are connected to each other through a mechanical connection and a connection must be established in order for the circuit breaker to work properly.

In terms of working principle, 3DU2L circuit breaker is designed to open or close the circuit automatically when the overload or short circuit current reaches the specified value. When the overload or short circuit current reaches the specified value, the main switch will be opened, thus disconnecting the circuit. At the same time, the auxiliary switch will be opened, which in turn will stop the power supply to the control circuits.

As far as application field is concerned, 3DU2L circuit breakers are widely used in industries such as electronics, automotive, telecommunications and other industries where high-level protection against short circuits, overloads and misoperations is required. They are also used to protect sensitive electronic components, protect against mechanical damage, and reduce the risk of fires.

3DU2L circuit breakers are renowned for their reliability, affordability and flexibility, enabling users to make the most out of their investment. They are easy to maintain, easy to install and able to provide excellent protection for electrical systems and control. They also come with a variety of features such as built-in surge protection and a manual reset switch which can be used to manually reset the circuit breaker after a fault has been detected.

In conclusion, 3DU2L circuit breakers are a reliable and reliable type of circuit breaker, with a wide range of applications and excellent protection against short circuits, overloads and misoperations. They are easy to maintain, simple to install and provide excellent protection for electrical systems and control.
