Engineering Analysis
A 30mA sensitivity is essential for human life protection as it interrupts the circuit within 300ms at 1x rated leakage current. The 10kA conditional short circuit rating allows this unit to withstand significant faults when paired with a backup MCB, while the 2-pole configuration ensures both phase and neutral are isolated during a trip. With a making and breaking capacity of 250A, the device manages heavy residential switching loads without contact welding.
