That 250 A full-scale value is the frame rating — the breaker's maximum continuous current before you need to consider the thermal derating curve: it holds 250 A through 50 °C, then steps down to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C (–). Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V (–). At typical 400 V distribution, the 121 kA SCCR gives substantial headroom for high-fault panels without cascading upstream breakers. The 4.5 kA at 690 V is a tail-off — this breaker is optimized for the 240–500 V range. That means it can report its status to a PLC or BMS without an add-on module — useful for remote monitoring on a production line. Dimensions: 181 mm height × 105 mm width × 86 mm depth (–). The 48 W maximum power loss needs to be factored into the enclosure thermal calculation, especially if multiple breakers are ganged.","metaTitle":"Siemens 3VA2225-5JQ32-0AK0 SENTRON MCCB, 250 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2225-5JQ32-0AK0 molded case circuit breaker, 250 A rated, 3-pole, 187 kA at 240 V.
