Engineering Analysis
The 300mA sensitivity is specifically engineered for fire protection in domestic settings where a 30mA device might cause nuisance tripping but higher current leakage could ignite flammable materials. With a 10kA conditional short circuit capacity, this unit handles significant fault energy when coordinated with an upstream MCB, while the 500A making/breaking capacity ensures the contacts remain intact during high-inrush events. The 2-module 36mm width allows for standard DIN rail integration without requiring excessive space in the distribution board.
