Engineering Analysis
A 100mA sensitivity level is specifically chosen for fire protection in residential distribution, as it detects leakage levels that could ignite materials without the nuisance tripping common in 30mA units. The 630A making and breaking capacity ensures the device can safely handle transient switching loads at the main incomer position. Using 4 poles (4P) provides complete isolation of all phases and the neutral line for comprehensive system safety.
