Circuit breakers are widely used in a variety of applications to protect electrical systems against overload and short circuits. The IPGH266-20628-2 is a type of circuit breaker manufactured by ABB specially designed for medium voltage applications. In this article, we will explore the IPGH266-20628-2’s application field and working principle.

Application Field

The IPGH266-20628-2 is suitable for use in electrical installations where three-phase power supply is required. It is suitable for medium voltage applications with rated current up to 690A and rated voltage up to 10kV. It is also designed with arc suppression technology for improved safety. The IPGH266-20628-2 is also suitable for industrial and commercial applications where reliable power supply is required.

Working Principle

The IPGH266-20628-2 works on the principle of air-magnetic circuit breakers. In this type of circuit breaker, an air-magnetic system is employed where the arc is quenched by a combination of air blast and a magnetic field. When the circuit breaker receives an overload current, the arcing contacts are opened and the arc is quenched by the air blast and magnetic field. This helps in preventing further damage to the electrical system.

The IPGH266-20628-2 also features trip free operation, which means that if the current increase beyond the rated value, the breaker will automatically trip and disconnect the power supply. This ensures that the system is not exposed to damage and provides enhanced safety.

Conclusion

The IPGH266-20628-2 circuit breaker is specially designed for medium voltage applications and features arc suppression technology for improved safety. It is suitable for use in electrical installations where three-phase power supply is required and features trip free operation for enhanced safety. With its reliable performance and advanced features, the IPGH266-20628-2 is the perfect choice for industrial and commercial applications.
