Circuit Breakers: SU2D50UC Application Field and Working Principle

Circuit breakers are electrical switches that are used to protect an electrical circuit from damage caused by overload or short circuit. Circuit breakers are essential components that function as the main safety device for many types of electrical circuits. Circuit breakers come in a variety of sizes, current ratings, voltage, and ratings. The SU2D50UC is a type of circuit breaker that is used for medium-voltage applications and provides a reliable solution for overcurrent protection.

Application Fields

The SU2D50UC circuit breaker can be used in a variety of applications due to its flexibility and durability. It is suitable for medium-voltage applications, such as industrial and commercial power systems and can be used in distribution networks, motor control circuit, and distribution system. The circuit breakeris UL-approved and is suitable for 480V and 600V systems and can withstand up to 15,000 amps of current.

Working Principle

The SU2D50UC circuit breaker is designed with a thermal-magnetic trip system. This system consists of two different mechanisms for protection: a thermal trip and a magnetic trip. The thermal trip works to protect the circuit from overheating by sensing any rise in temperature and automatically interrupting the electrical current. The magnetic trip works to protect the circuit from overload or short circuit by sensing any change in the current and automatically interrupting the electrical current. The trip system is designed to be adjustable, allowing the user to adjust the settings depending on the specific application.

Conclusion

The SU2D50UC circuit breaker is a reliable and durable choice for medium-voltage applications. Its thermal-magnetic trip system ensures reliable protection from overcurrent, short circuit and overload conditions. In addition, the adjustable features of the trip system provide customizable settings reach various levels of protection. The SU2D50UC circuit breaker is a great choice for any medium-voltage applications.
