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.","metaTitle":"Siemens 3VA2140-0HN32-0AA0 SENTRON MCCB, 40A, 3-Pole, ETU350","metaDescription":"Siemens 3VA2140-0HN32-0AA0 SENTRON molded case circuit breaker. 40A continuous, 3-pole, ETU350 trip unit. 440 kA breaking at 415 V.
