Engineering Analysis
The 30mA sensitivity rating is essential for residential environments as it trips in ≤40ms during high-leakage events, which is faster than the human body's threshold for respiratory paralysis. A 10kA breaking capacity ensures the device remains intact after interrupting significant fault currents at the main panel. The 4P pole configuration provides a switched neutral, which is vital for preventing voltage back-feed through the neutral line during a fault.
