Engineering Analysis
The Type AC 30mA sensitivity is vital for residential circuits because it detects sinusoidal leakage currents that can cause ventricular fibrillation in humans. With a 6kA breaking capacity, this device is engineered to survive the high thermal stresses of residential short circuits, while the 1P+N configuration ensures the neutral wire is switched for complete electrical isolation. The inclusion of a Class 3 energy limiting feature ensures minimal let-through energy during faults, protecting downstream wiring from degradation.
