What it is and what it does
The Siemens 3VA2325-6HL32-0DC0 is a SENTRON molded case circuit breaker (MCCB) rated for line-protection duty — the job of guarding a feeder or main against overload and short-circuit faults before they cascade downstream. It carries a continuous current rating of 250 A across the full ambient range from 40 °C up to 70 °C, so no derating curve to chase when the panel runs warm. The interrupting capacity at 240 V is 242 kA, which means it can safely clear a fault of that magnitude without rupturing — that's the number your coordination study needs to confirm against the available fault current at the installation point.
Ratings that drive the fit
Three poles, 250 A frame, and the interrupting curve steps down with voltage: 242 kA at 240 V, 187 kA at 415 V, 121 kA at 500 V, and 7.5 kA at 690 V. The 690 V figure is notably lower — if your system runs at that voltage, verify the available fault current is under that ceiling. The breaker ships with an undervoltage release (UVR) and two auxiliary switches (HQ type) factory-fitted, so it's ready for remote status and shunt-trip control without a separate accessory order. Trip indicator is not included; if visual flag confirmation matters for your panel walkdown, factor that into the BOM.
Panel fit and integration
Dimensions: 248 mm high, 138 mm wide, 110 mm deep. The 110 mm depth is the key number for enclosure depth — measure your gland plate clearance. It's a panel-mount MCCB, not a DIN-rail snap-on; plan for screw-mounting on a backplate. The undervoltage release coil and auxiliary switches are wired internally; verify your control voltage matches the UVR rating (not stated here, but standard for the SENTRON accessory family).
