Its breaking capacity of 187 kA at 240 V and 121 kA at 415 V tells you it can safely clear high-fault-current events without cascading upstream, which is the deciding spec for a panel with a high-available-fault utility transformer. ## Thermal derating — the real ampacity for your enclosure At 40 °C this MCCB carries its full 250 A rating, and it holds that rating through 50 °C — no derating needed in a typical ventilated panel. At 55 °C it drops to 238 A, at 60 °C to 225 A, at 65 °C to 213 A, and at 70 °C to 200 A. The maximum operating ambient is 70 °C; storage range is -40 °C to 80 °C. ## Breaking capacity across voltages — verify your fault level The 3VA2225-5JQ32-0DA0 delivers 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. For a 480 V panel (common in North America), the relevant figure is the 500 V rating at 75.6 kA — that is the SCCR you compare against the available fault current at the breaker's location. The sharp drop at 690 V (4.5 kA) tells you this is not a 690 V main breaker; it is a 500 V-class device. The breaker measures 105 mm wide, 181 mm high, and 86 mm deep. That 105 mm width (4.13 in) is a standard 3-pole MCCB footprint for this class — it fits Siemens SENTRON mounting plates and common DIN-rail adapters without extra panel rework. The 86 mm depth (3.39 in) means it clears most 200 mm-deep enclosures with room for wiring gutters.","metaTitle":"Siemens 3VA2225-5JQ32-0DA0 SENTRON MCCB, 250 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2225-5JQ32-0DA0 molded case circuit breaker, 250 A at 40 °C, 3-pole, 187 kA at 240 V.
