Engineering Analysis
The 30mA sensitivity is the critical threshold for human life protection, as it trips the circuit in ≤40ms at 5x Idn to prevent ventricular fibrillation. A 10kA breaking capacity is essential for modern distribution boards to safely extinguish high-energy arcs during major faults. Four-pole protection with a switched neutral ensures that the return path is fully isolated during a trip event, preventing potential back-feed hazards.
