Lifecycle status is current. The residual current element is type AC, rated 10 mA — sensitive enough for personal protection in wet locations but not so low it trips on normal leakage from filters or long cable runs. This is a 1P+N device — it switches the line conductor and provides residual current detection on both line and neutral, but does not switch the neutral. Supply can enter from top or bottom, which simplifies busbar routing in a crowded enclosure. Touch protection is built in.
At 40 °C it derates to 9.4 A, at 45 °C to 9.1 A, at 50 °C to 8.7 A, and at 55 °C to 8.1 A (–). If the panel runs warm — adjacent to a transformer or in a non-ventilated enclosure — size up one frame to stay inside the thermal curve.
Installation notes
Mounting position is any orientation.
This is an active, current-production Siemens SENTRON part. For volume or scheduled releases, a blanket PO with scheduled releases is the standard commercial posture.
