The interrupting ratings climb with voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That spread tells you the breaker is built for high-fault installations — the 121 kA at 415 V covers most European industrial distribution, while the 75.6 kA at 440 V handles North American 480 V panels with headroom. What you set at the factory is what you get. That keeps the part simple for panel builders who want a known coordination curve without field-adjustment risk.
The breaker holds its full 100 A rating from 40 °C through 50 °C, then begins to derate: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. No washdown rating; keep this behind a gland plate or enclosure door in wet environments.
The auxiliary contact block is factory-installed; the order code for the integrated auxiliary trip module is 3VA9608-0BB11 if you need a spare or replacement.
For compliance documentation: the SENTRON 3VA series carries UL 489, CSA C22.2 No. 5, and IEC 60947-2 certifications. RoHS and REACH declarations are available through Siemens Industry Online Support.
The 76.2 mm width is a standard 3-pole MCCB footprint — three 25.4 mm pole centers — so it fits existing bus-bar and lug layouts without re-drilling. Depth of 70 mm leaves clearance for rear-connected bus stabs or plug-in bases in switchgear.
