The Siemens SENTRON 3VA2225-5HL32-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, with a maximum breaking capacity of 187 kA at 240 V AC. At 415 V and 440 V the interrupting rating holds at 121 kA, dropping to 75.6 kA at 500 V and 4.5 kA at 690 V, so the voltage class of your distribution determines which rating governs the application. The continuous current rating is flat at 250 A from 40 °C through 50 °C ambient, then derates linearly to 213 A at 70 °C. For a panel running at 55 °C ambient — common in enclosed switchgear — the breaker is good for 241 A, so a 250 A feeder is still viable with a small margin. The maximum power loss of 50.5 W should be factored into enclosure thermal calculations, especially in sealed cabinets. The basic switch variant is 3VA2225-5HL32-0AA0, and this order code adds the UVR and auxiliary switches pre-installed.
The 86 mm depth (3.39 in) is shallow enough for enclosures, leaving room for wiring gutters and busbar connections behind the breaker.
