2DU2L

Circuit breakers are an important part of electrical systems, providing protection against the hazards of an electrical surge or overload. 2DU2L circuit breakers are specially designed to provide protection against both high-voltage surge and earth leakage currents by using two discs arranged in series. The discs are centered between a set of contacts, and when the circuit breaker is operated, a spring pushes one of the discs open, which causes the contacts to open up, thereby breaking the circuit and protecting devices downstream from being overloaded.

In terms of its application field, 2DU2L circuit breakers are widely used in residential areas, as well as industrial applications such as machine automation, power supply distribution, control box equipment, and many other applications. They are also widely used in hazardous areas to provide protection against electric shock and overvoltage. The most common uses for the 2DU2L circuit breakers are to protect against excessive currents, short circuits, overloads, and ground leakage.

The working principle behind 2DU2L circuit breakers is fairly simple. When a set current level is exceeded, such as a short circuit, the current-carrying conductor will open up and the circuit breaker will be activated, breaking the circuit and preventing damage from occurring to the connected devices. On the other hand, when the current no longer exceeds the threshold, the spring pushes the contact back together and the circuit is re-connected.

2DU2L circuit breakers are the preferred choice in many applications due to their reliability, safety, and robustness. They are also highly efficient, and can handle large current levels without creating dangerous sparks. In addition, they are relatively inexpensive, making them a cost-effective solution for protecting against excessive currents and surges.

In summary, 2DU2L circuit breakers are highly reliable, efficient and cost-effective solutions for protecting against electrical surges, overloads, and ground leakage. They are widely used in both residential and industrial applications, providing reliable and secure protection and enabling a safe operating environment.
