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. Trip indicator is not included; if visual flag confirmation matters for your panel walkdown, factor that into the BOM.
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).
