Its interrupting capacity is the headline spec: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V. The continuous current rating holds at 250 A from 40 °C through 50 °C ambient, then derates linearly down to 213 A at 70 °C. The 2500 A frame means the internal mechanism and contacts are built for that maximum current; the 250 A continuous rating is the thermal-magnetic or electronic trip unit setting. An undervoltage release (UVR) is fitted as standard — the auxiliary release design is an undervoltage release (UVR). The basic switch variant is 3VA2225-6HN32-0AA0, which is the same breaker without the UVR; this order code includes it.
That 105 mm width (4.13 in) is the standard 3-pole MCCB footprint for this SENTRON frame size — it occupies three 35 mm DIN spaces if using a DIN-rail adapter, or bolts directly onto a mounting plate in a switchboard. The 86 mm depth (3.39 in) leaves room for rear-connected busbars or cable lugs without crowding the gland plate.
