Engineering Analysis
The 100mA residual current sensitivity is specifically selected for fire protection in residential distribution boards where 30mA might cause nuisance tripping. A 10kA breaking capacity ensures the device can safely interrupt high-fault currents at the main incomer without catastrophic failure. The 4P configuration with a switched neutral is vital for isolating all live conductors during a fault, preventing back-fed voltages in 415V systems.
