The 100mA sensitivity level is specifically selected for fire protection, as it detects leakage currents that could ignite surrounding materials before a standard MCB trips. With a 10kA breaking capacity, this RCBO safely interrupts high-magnitude fault currents at the main distribution point, preventing damage to the downstream wiring. The 4P configuration ensures a switched neutral, providing total isolation of the circuit during a trip event to prevent potential neutral-to-earth faults.
