Circuit Breakers

Circuit breakers are essential components in the operation of electrical systems. They are designed to protect electrical equipment from over voltage or short circuit damage that could cause system or equipment damage, or even fire. Circuit breakers also help to control the flow of electricity and prevent power overloads in large commercial and industrial facilities. SU2D6UC is one such circuit breaker designed for a wide range of applications.

SU2D6UC Application Field and Working Principle

The SU2D6UC is a medium voltage circuit breaker with a voltage range of 24kV-40.5kV, an insulation level of 12kV, and a current range of 1000-3000A. This circuit breaker is mainly used to protect medium voltage power cables and medium voltage transformers in large commercial, industrial and power plants, as well as medium voltage power systems. It can be used in single, double and triple pole applications, as well as in high power plants where its power handling capabilities are especially useful.

In terms of its operation, the SU2D6UC circuit breaker contains two primary parts: the contact system and the arc chute system. The contact system is made up of a stationary contact and a movable contact, and is designed to open or close electric circuits. The arc chute system is designed to quench electric arcs, which are generated when two electric contacts open, and to reduce the power of electric arcing. This system uses a combination of air, water and other materials to create a cooling system for the electric arc.

Additionally, the SU2D6UC circuit breaker has several protection and control functions, such as short circuit protection, over-current protection, and over-voltage protection. It also has a differential current protection function, which helps detect and prevent over-currents in large networks. Furthermore, this circuit breaker is equipped with several advanced features such as remote control, metering, interlocking, and fault monitoring.

The SU2D6UC circuit breaker has proven to be an effective and reliable device in the protection and control of electrical systems. Its protection and control functions ensure that the circuit breaker is able to detect and interrupt electric faults quickly and safely, while its metering and interlocking functions enable better coordination between switches and other devices in power systems. With its robust design and reliable performance, the SU2D6UC circuit breaker is suitable for a wide range of applications.
