Breaking capacity is 75.6 kA at 240 V AC, 52.5 kA at 415 V AC, 32 kA at 440 V AC, and 7.5 kA at 690 V AC — so at typical 400 V class panel voltages it clears fault currents up to 52.5 kA without upstream fuses. That's enough for most industrial main or feeder duty where the transformer is sized under 2 MVA. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm high — a standard 3-pole MCCB footprint that fits SENTRON mounting plates and most DIN-rail adapters. Front protection is IP40, meaning it's splash-proof from the front but not sealed against dust ingress from the sides or rear.
Built-in auxiliary and undervoltage release
It also carries two auxiliary switches (HQ type) for remote status indication — one normally open, one normally closed. These are wired back to a PLC input or panel lamp to signal whether the breaker is closed or tripped. The integrated auxiliary trip order code for replacement is 3VA9608-0BB11.
Above that it derates: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C.
The lifecycle stage for this order code is listed as current — meaning Siemens still manufactures it as an active catalog item. No phase-out or last-time-buy notice is attached to this variant. For a BOM freeze or long-term project, this is a stable line to specify.
