The Siemens 5SU1356-0DA10 is a combined residual current device and miniature circuit breaker (RCD/MCB combo) — an FI/LS protector. It's built for final-circuit protection where both overcurrent and earth-fault protection are needed in one 1+N-pole unit, saving a DIN-rail slot compared to separate devices. The pig-tail connection means the neutral lead exits the device as a flexible wire, intended for the incoming neutral busbar in a consumer unit or distribution board. That's a common fit in European-style DIN-rail enclosures.

What does the description FI/LS-PROTECTOR TYPE AC (WS), D=70MM IFN 30MA, 6KA, 1+N-POLEE B 10A PIG-TAIL mean?
It's a combined RCD/MCB (FI/LS = Fehlerstrom-/Leitungsschutzschalter in German). Type AC means it detects sinusoidal AC fault currents only. D=70mm is the DIN-rail module width. IFN 30mA is the rated residual operating current. 6kA is the short-circuit breaking capacity. 1+N-pole means it switches the line and provides neutral switching. B 10A is the overcurrent trip curve and rated current. Pig-tail means the neutral connection is a flexible lead.
