SENTRON 3VA2140-0HN32-0AA0 — 40 A MCCB with ETU350, 440 kA at 415 V
The 690 V rating covers 600 V class systems common in North American and some European industrial plants.
That 105 mm width is the standard 3-pole MCCB footprint for the SENTRON 3VA2 frame — it fits the same panel cutout and busbar spacing as other 3VA2 3-pole breakers.
Trip unit and protection features
The ETU350 is an electronic trip unit with adjustable overload (Ir) and short-circuit (Isd, Ii) settings. It does not include ground-fault monitoring or grounding protection — this is a straight line-protection breaker. No undervoltage release, no communication function, no voltage trigger, and no trip indicator. It's a basic, reliable MCCB for feeder protection where you don't need auxiliary signaling or remote monitoring. Power loss is rated at 1.2 W maximum — negligible for panel thermal budgeting.
