Engineering Analysis
The 100mA sensitivity is optimized for fire protection in residential circuits where 30mA might cause nuisance tripping but higher levels remain unsafe for property. A 10kA breaking capacity ensures the device remains intact during high-energy short circuit events at the main incomer. Dual-pole (2P) configuration with a switched neutral provides complete isolation of the circuit during a fault condition.
