Circuit Breakers

Circuit breakers are invaluable electrical components that are used to protect electrical circuits from overloads and short circuits. The IEG1-1-51-2.00-A-01-V is a common type of circuit breaker. Here, we\'ll explore its application field and working principle.

Application Field

The IEG1-1-51-2.00-A-01-V circuit breaker is designed to provide reliable protection against short circuits, overloads, and groundwork faults. The device is typically mounted in panels and is suitable for indoor installations in low voltage systems. It is commonly used in rigid busbar systems.

The IEG1-1-51-2.00-A-01-V is rated for a maximum voltage of 600V and a maximum current of 400A. It can provide a maximum short circuit breaking capacity of up to 200kA. It is also equipped with a trip indicator to provide visual indication when an overload or short circuit occurs.

Working Principle

The IEG1-1-51-2.00-A-01-V circuit breaker relies on a pair of reverse biased semiconductor devices (SCRs) to interrupt the flow of current when an overload or short circuit occurs. The SCRs are connected in series, with each one connected to one side of the breaker.

When the current exceeds the circuit breaker\'s rated value, the voltage across the two SCRs increases. This increase in voltage causes the SCR devices to become conductive, which in turn creates an arc that interrupts the current flow. Once the current flow is stopped, the arc is extinguished, which allows the breaker to reset and restore power to the circuit.

Conclusion

The IEG1-1-51-2.00-A-01-V circuit breaker is an invaluable tool in the protection of electrical systems. It is designed to provide reliable protection against short circuits, overloads, and ground faults. It is rated for a maximum voltage of 600V and a maximum current of 400A and provides a maximum short circuit breaking capacity of up to 200kA. The device operates by relying on a pair of reverse biased SCRs which interrupt the current flow when an overload or short circuit occurs.
