The Siemens 3VA2225-6KP32-0CC0 is a SENTRON molded case circuit breaker rated for 250 A continuous at 40 °C, with a maximum breaking capacity of 242 kA at 240 V AC. At 415 V and 440 V it still holds 187 kA, and at 500 V it delivers 121 kA, dropping to 4.5 kA at 690 V. The 250 A frame is the same across the 40–50 °C range; above that it derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C — so if your panel ambient runs hot, size for the derated figure, not the nameplate.
Built-in release and communication
Communication function is present, so it can integrate with a higher-level monitoring system over the SENTRON bus or a compatible gateway.
