Engineering Analysis
The 300mA sensitivity is optimized specifically for fire protection in residential distribution boards where 30mA devices might cause nuisance tripping. A 16A rated current paired with a B-curve trip characteristic ensures rapid disconnection during low-level short circuits, while the 4P switched neutral prevents potential differences in the return path. The 10,000-cycle mechanical endurance ensures long-term reliability for Indian households with fluctuating power conditions.
