It carries a breaking capacity of 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V — so the same frame can handle high-fault utility feeds (240 V) down to a 690 V motor branch without swapping the breaker. For a data-center or industrial panel where ambient inside the enclosure can hit 50–55 °C, you size the load at 238 A (55 °C) or 225 A (60 °C) — the breaker itself doesn't lose headroom until you cross 50 °C.
Panel-fit and auxiliary integration
Footprint: 105 mm wide, 181 mm high, 86 mm deep — standard 3-pole MCCB envelope for a 250 A frame. If you are replacing an existing 3VA2225-5JQ32-0AK0 in a panel, the physical mounting and bus-bar centers are identical — same 105 mm width, same depth — so no rewiring or drilling is needed. The difference is the trip unit and auxiliary contact configuration; verify the control wiring matches the UVR and alarm contacts.
Approvals and compliance documentation
The SENTRON 3VA series carries UL, CSA, and IEC certifications as standard for the platform. RoHS and REACH declarations are published by Siemens for the 3VA family; the specific order code is covered under those blanket compliance documents. No separate per-unit paperwork is required for EU or North American installations.
