What this MCCB carries and what it means for your panel
The Siemens SENTRON 3VA2225-7HL32-0CH0 is a 3-pole molded case circuit breaker rated for a continuous current Iu of 250 A. That 250 A holds flat from 40 °C through 50 °C ambient — no derating needed in a typical warm panel — then steps down to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. So if your enclosure runs hot, you still have a solid 213 A of headroom at the upper end of the operating range. The interrupting ratings tell you where this breaker can sit in the fault-current chain: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 6.3 kA at 690 V. That 330 kA at 240 V is a main or large-feeder class rating; the 6.3 kA at 690 V still covers most industrial loads at that voltage. The rated insulation voltage Ui of 800 V confirms the internal clearances are designed for 690 V systems. This is a line-protection version (product version field) with an ETU320 electronic trip unit — no communication function, no phase-failure detection, no ground-fault monitoring. It ships with an undervoltage release (UVR) as the auxiliary release, plus a 2-auxiliary-switch + 1-trip-alarm-switch HQ auxiliary contact block. The integrated auxiliary trip module is order code 3VA9608-0BB24; the supplied basic switch is 3VA2225-7HL32-0AA0.
Mounting and integration into a 3-pole footprint
Breaker measures 105 mm wide, 181 mm high, and 86 mm deep. Maximum power loss is 50.5 W. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Trip indicator is present. Latching endurance is rated at 20,000 operations.
How this compares to the 3VA1112-5EF32-0CA0
The 3VA1112-5EF32-0CA0 is a smaller-frame SENTRON MCCB — lower continuous current, different trip unit, and a narrower width. It will not drop into the same panel cutout or bus connection as this 3VA2225-7HL32-0CH0 without rewiring and re-bussing. The 3VA2225 is the 250 A frame; the 3VA1112 is a 160 A or lower frame. If your BOM calls for the 250 A rating, the 3VA1112 is not a functional second-source — you need the 3VA2225 frame.
