Engineering Analysis
A 30mA sensitivity level is vital for domestic protection because it trips within 300ms at 1x Idn to prevent cardiac arrest from leakage. The 10kA conditional short circuit rating ensures the 180g unit survives high-current faults when paired with a backup MCB. The 2P configuration with solid neutral protection provides complete isolation of the 50Hz single-phase supply during trip events.
