Engineering Analysis
The 30mA sensitivity is essential for life safety as it trips @ 1x Idn in ≤300ms, preventing ventricular fibrillation during accidental contact. The 6kA breaking capacity handles high-energy faults at the final circuit level, while the C-curve trip characteristic accommodates typical residential inductive loads. The 2P configuration with a switched neutral ensures total isolation of the faulty circuit, which is vital for modern TN or TT earthing systems.
