That interrupting capacity is the headline number here — 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. Those are short-circuit current ratings (SCCR) you can coordinate downstream gear against, which matters when you're feeding a panel full of motor starters or smaller branch breakers. The 70 mm depth, 105 mm width, and 158 mm height are standard 3VA frame dimensions — it fits the same footprint as other SENTRON 3VA breakers in the 250 A range. Power loss is 57 W maximum at rated load — that's heat that has to leave the enclosure. In a sealed panel with multiple breakers ganged together, that number drives the ventilation or derating calculation. ## Integration notes This is a line-protection breaker, not a motor-protective device — it's designed for feeder duty, not overload protection of a specific motor. The basic switch part number is 3VA12256EF320AA0 — that's the internal switching mechanism, not something you'd order separately unless you're rebuilding a damaged unit.","metaTitle":"Siemens 3VA1225-6EF32-0AC0 SENTRON MCCB, 250A, 220kA IC at 2","metaDescription":"Siemens SENTRON 3VA1225-6EF32-0AC0 molded case circuit breaker, 3-pole, 250A rated, 220 kA interrupting at 240V.
