Engineering Analysis
A 30mA sensitivity rating is mandatory for human life protection because it interrupts the circuit before leakage currents can cause cardiac failure. The 630A making and breaking capacity ensures the device safely handles switching surges at the main incomer while the 10 kA conditional short circuit rating provides robust coordination with upstream MCBs. Utilizing 2P poles allows for a solid neutral connection, ensuring the entire 240V 50 Hz circuit is isolated during an earth fault.
