Circuit breakers are a critical component of electrical equipment that prevents overload and short circuit conditions. The SU3D6UC breaker is a particular type of circuit breaker that is most commonly used in commercial, industrial, and institutional applications. This article will discuss the application field, working principle, and the advantages of using this type of breaker.

Application Field

The SU3D6UC breaker is mainly used in commercial, industrial, and institutional applications. It is a type of three-phase circuit breaker that is rated for 600VAC/DC and is suitable for equipment rated up to 450A. It can be used as a main or branch circuit breaker and is also suitable for use with alternative energy sources such as solar energy. In addition, it can be used in a range of applications, from simple residential settings to large commercial or industrial settings.

Working Principle

The working principle of the SU3D6UC breaker is based on the principle of magnetic separation. The breaker comprises a series of connected poles, one of which contains a solenoid coil. When an overload or a defect in the current flow occurs, the resulting fault causes an excessive current to flow through the coil. This causes a magnetic force to be created, which then causes a circuit breaker trip, thus preventing further damage and disruption.

The advantage of using a three-phase breaker instead of a single-phase device is that it can handle more load and is more efficient in controlling the current, as it can detect and trip at lower levels of current than a single-phase breaker. Another advantage is that, due to its design, the SU3D6UC breaker is resistant to shock and humidity, making it suitable for use in harsh environments.

Advantages

One of the main benefits of using the SU3D6UC breaker is that it is cost-effective. This breaker is easy to install and does not require additional wiring or supports, meaning installation and maintenance costs are relatively low. It is also highly reliable and can reach over 1000 operations in a single year, making it an ideal choice for high-frequency operations. In addition, it is a safe and durable breaker, as it has temperature-controlled coil design that can withstand operating temperatures of up to 105 degrees Celsius.

Furthermore, the easily adjustable trip settings make it simple to monitor and protect the circuit from potential overloads. An adjustable trip limit allows the user to set the maximum level of current the breaker will tolerate before tripping, ensuring that the circuits are properly protected. This feature is especially useful in emergency situations where it can be used to quickly identify and distinguish false alarms from true emergency conditions.

The SU3D6UC breaker is also energy efficient, with low current leakage and low-power consumption. This helps to reduce overall energy costs as the breaker is consuming less energy and helps to reduce carbon emissions. Finally, the SU3D6UC breaker has been tested for use in hazardous environments, making it suitable for use in classified locations such as oil rigs, chemical plants, and mining sites.

In conclusion, the SU3D6UC breaker is a reliable and efficient device used in commercial, industrial and institutional applications. It is cost-effective, easy to install and maintain, and can withstand harsh environments. It is energy efficient and able to provide reliable protection against overloads and faults. Finally, its adjustable trip settings enable users to customise its operation according to their requirements, making it ideal for most applications.
