It's a current-production part — still in active manufacture, so no scavenging needed for new builds or spares. Three poles, electronic ETU350M trip unit with adjustable trip classes 10A, 10E, and 20E — that covers most standard motor start profiles from quick-start pumps to higher-inertia conveyors.
Breaking capacity — the real number that matters for selectivity
The 440 kA at 415 V is the headline, but the 187 kA at 690 V is what you care about if you're feeding a 690 V drive or transformer. That's a serious interrupting rating — it'll hold fault current through a high-capacity transformer secondary without cascading upstream.
Footprint is 105 mm wide by 181 mm tall by 86 mm deep — standard 3-pole MCCB envelope for the SENTRON 3VA2 family. If you need those add-ons, you're looking at a different variant in the 3VA2 range.
Lifecycle status is current — no end-of-life notice, no last-time-buy clock ticking. That means you can spec it into a BOM without worrying about a forced redesign next year.
