The 30mA sensitivity level is essential for domestic safety as it is calibrated to trip within ≤300ms at 1x Idn, preventing the physiological effects of electric shock. Its 6kA conditional short circuit capacity and 500A making/breaking capacity provide the necessary robustness to withstand upstream faults in standard Indian 50Hz grids. The inclusion of a solid neutral in the 2P configuration ensures a reliable reference point for current imbalance detection, even in imbalanced residential loads.
