Its interrupting capacity reaches 330 kA at 240 VAC and 242 kA at 415/440 VAC — enough for high-fault utility feeds or transformer secondaries where SCCR headroom matters. That means the panel builder gets both remote status and a dedicated alarm contact without adding an external module. ## Derating and thermal limits Rated 250 A from 40 °C to 50 °C ambient, the breaker derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. If your panel internal ambient runs above 50 °C, size the load accordingly — the 250 A nameplate holds only up to that point. Maximum power loss is 50.5 W. In a sealed enclosure with multiple breakers, that heat adds up — factor it into your thermal budget rather than assuming the nameplate current is usable everywhere. ## Footprint and panel integration That 86 mm depth is the key dimension for shallow backpanel enclosures — verify gland-plate clearance before committing the layout. The 3-pole block occupies three module widths (105 mm total), so it fits the same grid as other 3VA frame sizes.","metaTitle":"Siemens 3VA2225-7KP32-0DH0 SENTRON MCCB, 250 A, 3P, 330 kA a","metaDescription":"Siemens SENTRON 3VA2225-7KP32-0DH0 molded case circuit breaker, 250 A continuous, 3-pole, 330 kA at 240 VAC.
