Circuit Breakers

A circuit breaker, also known as an interruptor, is a device designed to protect an electrical circuit from damage caused by excessive current, or shorts, and to automatically disconnect the circuit when an overload or short occurs. Circuit breakers are used to protect electrical circuits in homes, industrial installations, and other electrical systems.

The IEG1-1-72-15.0-91-V is a circuit breaker specifically designed for use in high voltage applications. This particular model is rated for 15kV, up to 160A, and is suitable for both direct and indirect operation in either 50/60 Hz AC or DC circuits. The circuit breaker can be operated in single or three phase circuits, and is rated for isolation, reverse power, and interrupting of fault currents.

Working Principle

The working principle of the IEG1-1-72-15.0-91-V circuit breaker is based on an overcurrent sensing device such as a thermal or an electromagnetic sensor. The overcurrent sensing device triggers an electrical switch or circuit breaker when the current exceeds its rated value. The switch trips, opening the circuit and preventing further current from flowing.

The circuit breaker can also be manually operated by pressing a button or turning a switch. Manual operation allows for the isolation of a fault or for resetting a tripped circuit breaker. Additionally, some circuit breakers are designed with an automatic reset mechanism, which allows the circuit breaker to reset itself to its rated value after a certain amount of time has passed.

Application Field

The IEG1-1-72-15.0-91-V is suitable for use in a variety of applications including residential, industrial, and commercial settings. This particular model is well-suited for use in extremely high voltage systems, such as those found in power distribution grids. It has been certified to meet international standards, and is UL and CUL approved.

Aside from power distribution, this circuit breaker is also suitable for use in other industrial and commercial applications. This includes the protection of wiring in large machinery, pumping stations, and motors. It is also suitable for use in marine and aerospace applications, as well as in factory and laboratory environments.

Conclusion

The IEG1-1-72-15.0-91-V circuit breaker is an excellent choice for high voltage applications, whether it is for power distribution or for the protection of wiring in other industrial and commercial installations. This circuit breaker is designed to operate efficiently and securely, providing reliable protection against electrical accidents by automatically disconnecting the circuit when an overload or short occurs. Additionally, it is easy to install and operate, ensuring it is suitable for a variety of applications.
