ABB DS301C-C25/0.03 Specifications, Features & Compatibility Guide

The 30mA sensitivity is vital for life safety, as it trips instantaneously during leakage to prevent cardiac arrest. A 6kA breaking capacity ensures the device can safely interrupt high-fault currents at the distribution point, while the switched neutral poles provide complete isolation. The Type C trip curve is optimized for residential loads that experience moderate inrush currents.
