That 105 mm width is three-pole wide — standard for a 250 A frame in a distribution board. Communication function is built in, and a motor-drive extension is optional for remote tripping or re-closing. Lifecycle stage is marked as current — meaning Siemens still lists it as an active catalog number with no announced end-of-life. That is the cleanest procurement scenario: no LTB window to chase, no successor to qualify. If you are freezing a BOM for a multi-year panel run, this is a stable line item.","metaTitle":"Siemens 3VA2225-7KQ32-0AA0 SENTRON MCCB, 250 A, 3-Pole, ETU8","metaDescription":"Siemens 3VA2225-7KQ32-0AA0 SENTRON molded case circuit breaker, 250 A rated, 3-pole, ETU860 trip unit, 330 kA at 240 V.
