It protects a single-phase outgoing circuit against overloads, short-circuits, and earth faults, all in one DIN-rail package. The integrated 30 mA earth-leakage protection covers personnel shock risk per IEC 61009-1. The limitation class 3 rating means it limits let-through energy well, helping downstream coordination.
