Engineering Analysis
The 100mA sensitivity level is specifically chosen to provide a balance between preventing electrical fires and avoiding nuisance tripping in residential circuits. A 630A making and breaking capacity allows the device to safely handle the high inrush currents typical of domestic appliance startups. The 4P configuration is essential for 240V systems as it switches the neutral line to ensure zero potential on all load-side conductors during a trip.
