Engineering Analysis
The 100mA sensitivity (Type AC) is a critical threshold for fire prevention, as it stops leakage currents that generate heat without triggering standard breakers. With a 630A making and breaking capacity, the device maintains structural integrity during fault connection, while the 10kA conditional short circuit rating ensures safety when coordinated with upstream MCBs.
