IEG11-27486-2-V Circuit Protection

Circuit breakers are electrical safety devices used to break an electrical circuit with the purpose of preventing unwanted high current flow and potential circuit damage or hazards. IEG11-27486-2-V is a type of circuit breaker designed to detect ground fault current and disconnecting the power to the device or circuit when a fault is detected.

Application Field

IEG11-27486-2-V is suitable for single-phase or three-phase AC circuit with operating voltage up to 690V AC, operating frequency up to 50-60Hz and rated current 40-63A. It is mainly used for over-current and earth leakage protection for residential and commercial applications.

Working Principle

The IEG11-27486-2-V circuit breaker works by detecting an earth leakage in the connected device or circuit and triggering the current to be disconnected after a pre-defined time interval. The breaker has a built-in differential transformer, which will measure the current imbalance between phase and phase, neutral, and earth. When the current difference between these three lines is judged to exceed the pre-defined leakage current, the built-in time delay mechanism in the breaker will trigger the breaker to disconnect the circuit.

Conclusion

IEG11-27486-2-V circuit breaker is a device designed to detect ground fault current and disconnect the power in case of a fault. This type of breaker is vastly used in residential and commercial applications and provides reliable over-current and earth leakage protection. The device works by analyzing the current imbalance in the circuit and triggering the breaker in case of a pre-defined current threshold.
