Circuit Breakers

IEGH6666-1REC4-72-25.0-01-V is a type of circuit breaker. Circuit breakers are protective devices that are designed to be used in electrical circuits in order to protect the circuit from overcurrent and short circuits. In other words, circuit breakers are designed to detect the probability of a failure or malfunction and to respond quickly by disconnecting the circuit to prevent damage to the equipment or system.

Application Field

IEGH6666-1REC4-72-25.0-01-V circuit breakers are designed for medium-voltage applications. This type of circuit breaker is used in industrial, commercial, and residential power systems where over-current or short-circuiting protection is required. It is commonly used for primary protection of circuits with currents of up to 25kA.

Working Principle

The IEGH6666-1REC4-72-25.0-01-V circuit breaker works by sensing the electrical current in the circuit and responding accordingly. When the current reaches its specified level, the circuit breaker trips, disconnecting the circuit and protecting it from damage. The circuit breaker has two parts: the sensing unit and the trip element. The sensing unit is responsible for monitoring the current and delivering a signal to the trip element when the pre-determined threshold of current has been reached. The trip element then trips the circuit breaker, disconnecting the circuit.

The IEGH6666-1REC4-72-25.0-01-V circuit breaker also includes multiple features to ensure that the circuit is protected from damage in the event of a short circuit or overload. This type of circuit breaker also features an adjustable time-current curve (TCC) which allows for trip times to be adjusted based on the application requirements. The adjustable trip times enable the circuit breakers to respond to faults quickly and efficiently.

Conclusion

The IEGH6666-1REC4-72-25.0-01-V circuit breaker is designed for use in medium-voltage applications, and it can provide protection from overcurrent and short-circuiting. It is a reliable device that has multiple features, such as an adjustable TCC, to ensure that the circuit is protected from damage. This type of circuit breaker is an effective way to protect electrical circuits from damage due to excessive currents.
