Breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V; at 690 V it still manages 11.9 kA. That spread means it can sit at the main or branch in a 480 V panel and still interrupt a serious fault without the arc flash climbing upstream.
At 55 °C it derates to 19.2 A, at 60 °C to 18.8 A, at 65 °C to 18.4 A, and at 70 °C to 18 A. The front face is IP40, so it's fine inside a closed panel; no washdown rating, so keep it out of wet zones.
Width is 76.2 mm (roughly 3 inches), depth 70 mm, height 130 mm. That footprint matches the standard SENTRON 3VA platform — if the panel was laid out for a 3VA11 frame, this drops in on the same mounting holes and bus connections.
Lifecycle stage is current — Siemens still builds this exact variant. No phase-out notice, no last-time-buy. For a BOM line that needs an active MCCB with a known interrupting rating at multiple voltages, this part is a straight spec-in.
