Breaking capacity runs from 242 kA at 240 V down to 4 kA at 690 V — the 242 kA figure at 240 V is the headline interrupt rating, meaning this breaker can safely clear a fault of that magnitude at that voltage without welding contacts or rupturing the case. The 3VA2 frame is the compact, high-performance tier of the SENTRON MCCB family, designed for panel builders who need high interrupting capacity in a standard footprint.
Above 50 °C it steps down: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. The 690 V breaking capacity is 4 kA. The ETU350 trip unit is an electronic (not thermal-magnetic) release, which gives better accuracy and adjustable trip settings. It is configured for line protection — meaning it protects cables and busbars, not motor overloads — and has no voltage trigger or communication function.
Where it goes in the panel
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — the 105 mm width is a standard 3-pole MCCB footprint that fits most panel layouts without re-spacing busbars. Maximum power loss is 16 W at rated current — a modest figure that keeps heat rise manageable in a closed panel, but worth checking against your enclosure's thermal budget if you are ganging several breakers.
The basic switch (the breaker without auxiliaries) is order code 3VA2010-6HN36-0AA0, and the integrated auxiliary trip module is 3VA9608-0BB11. If you are stocking spares, those sub-assemblies are the service-level components.
