Circuit breakers are devices that protect electrical systems, machines, and components from damage caused by overloads, short-circuits, or other faults. 2D20UM is a type of circuit breaker with advanced features, which can be used in a variety of application fields. This article will look at the application field and working principle of the 2D20UM circuit breaker.

Application Field of 2D20UM

The 2D20UM circuit breaker is designed for use in residential, commercial and industrial applications. It is one of the most reliable and cost-effective circuit breakers available, and is used in a variety of applications, including vehicle and home appliance circuit protection, HVAC systems, electronic circuits, and industrial equipment. It is suitable for use in both new and existing installations, and is also suitable for use as a replacement for older circuit breakers.

The 2D20UM has a voltage rating of 250V and can handle up to 18A of current. The device is designed to trips at a fixed current overload and short circuit of 10-18A within a fraction of a second. The device also has adjustable current settings over the 0.1A-18A range. It is also equipped with an overload indicator that can be used to help diagnose potential issues with the circuit.

Working Principle of 2D20UM

The 2D20UM circuit breaker operates by interrupting the current flow in the circuit when an overload or short circuit is detected. This is accomplished by the use of a bimetallic element, which is a strip of metal with two different types of metal. Heating in an electric current will cause the two metals to expand at different rates, which causes the strip to bend. When the bimetallic element bends, it triggers the circuit breaker to open, interrupting the current flow.

The 2D20UM also features a resetable trip lever, which can be used to reset the circuit breaker if an overload or short circuit occurs. When the reset lever is pushed, the circuit breaker is reset and can be used again. This feature can be very useful in diagnosing issues with the circuit, as it allows technicians to reset the breaker and monitor the circuit for any potential issues.

Conclusion

The 2D20UM circuit breaker is a versatile and reliable device that can be used in a wide variety of applications. It is suitable for use in both residential and commercial installations, and can handle up to 18A of current. The device is designed to trip quickly when an overload or short circuit occurs, and is also equipped with a resetable trip lever. This allows technicians to quickly diagnose issues with the circuit and reset the breaker for further inspection. Overall, the 2D20UM is an excellent choice for circuit protection and is suitable for both new and existing installations.
