Engineering Analysis
The 30mA sensitivity is essential for life safety as it trips within ≤300ms at 1× Idn, effectively cutting power before a shock becomes lethal. A 6kA breaking capacity ensures the device can safely interrupt faults at the residential distribution board level, while the 4P configuration provides simultaneous protection for all three phases and the switched neutral.
