Rated breaking capacity hits 220 kA at 240 V, dropping to 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. At 415 V — the common industrial distribution voltage — 154 kA gives substantial SCCR headroom for high-fault panels. That level supports full selectivity with downstream 50 kA or 65 kA MCCBs without forcing a series-rated compromise; the upstream breaker clears before the downstream device reaches its limit. The 690 V figure (17 kA) matters for 600 V class installations in North American or marine plants. Above that, derating begins: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C. The thermal-magnetic release (TM240) is calibrated at 40 °C; the thermal element tracks ambient, so in a hot panel the breaker trips earlier on overload, which is the intended behavior. Dimensions: 158 mm height, 140 mm width, 70 mm depth. Four-pole frame, so width is the critical slot dimension — 140 mm matches the standard 4-pole MCCB cutout in most Siemens SENTRON and ALPHA distribution panels.","metaTitle":"Siemens 3VA1225-6GF42-0AJ0 SENTRON MCCB, 250 A, 4-Pole, 220","metaDescription":"Siemens 3VA1225-6GF42-0AJ0 SENTRON molded case circuit breaker, 250 A rated continuous current, 4-pole, 220 kA at 240 V.
