Engineering Analysis
A 30mA sensitivity rating is critical for residential safety as it is the threshold required to protect human life from cardiac fibrillation during accidental contact. The 630A making/breaking capacity ensures the device can safely manage high-current connecting and disconnecting events without internal welding. Providing 4P protection across four modules (72mm width) allows for a complete isolation of all phases and the neutral line in three-phase home wiring.
