Circuit breakers are an important part of a home\'s electrical system, ensuring that the electrical system is safe and protected from overloads. 2DU20L is an important type of circuit breaker which is widely used in industrial and commercial applications. This article will provide an overview of the 2DU20L application field and working principle.

The 2DU20L is a type of differential-type residential circuit breaker. It is designed to interrupt fault current and or excess rise of current in a circuit. It is typically used to protect household circuits from overloads and short circuits. The operating range of the 2DU20L is from 0.15 to 5 amps. This circuit breaker can be found in many areas such as residential buildings, commercial buildings, and industrial production lines. It is also widely used in automotive and electrical engineering.

The 2DU20L circuit breaker is typically composed of a housing, contact, core, spring, and arc-quenching medium. The housing is made of insulating materials such as Bakelite and PFA. The contacts are either reed contact or flat contact, depending on the type of 2DU20L circuit breaker. The core is usually made of pure or alloyed copper or silver and can be either plunging or adjustable. The spring is designed to keep the contact in close contact with the core. The arc-quenching medium is a special material placed between the spring and the contact in order to help extinguish the arc.

The working principle of the 2DU20L is based on the differential principle. When the current in the circuit reaches a certain value, the magnetic field generated by the current\'s flow causes the core to open. This causes the spring to be compressed and the contact to be disconnected from the core. As a result, the flow of current is stopped and the circuit breaker is tripped. Differential-type circuit breakers are extremely reliable and feature a high breaking capacity, a wide range of breaking capacity, and a high speed of operation.

The 2DU20L circuit breaker has a wide range of applications in residential buildings, commercial buildings, and industrial production lines. It is best suited for applications that require a high breaking capacity and a wide range of breaking capacity. It is also popular in automotive and electrical engineering applications due to its reliability and high speed of operation. The 2DU20L is a reliable and efficient solution for protecting circuits from overloads and short circuits.

In conclusion, the 2DU20L is an important type of circuit breaker which is widely used in various applications. It is composed of a housing, contact, core, spring, and arc-quenching medium. The working principle of the 2DU20L is based on the differential principle and it features a high breaking capacity, a wide range of breaking capacity, and a high speed of operation. It is best suited for applications that require a high breaking capacity and a wide range of breaking capacity. It is also popular in automotive and electrical engineering applications due to its reliability and high speed of operation.
