Engineering Analysis
A 30mA sensitivity is essential for personnel protection as it disconnects power before leakage reaches levels dangerous to the human body. The 10kA breaking capacity ensures the device remains functional after clearing major short circuits, while the 4P configuration provides comprehensive switched neutral protection for balanced safety. With an impulse withstand voltage of 4kV, the unit maintains stability against transient voltage spikes common in residential grids.
