The Siemens SENTRON 3VA2225-5KP32-0JA0 is a 3-pole molded case circuit breaker rated 250 A continuous at 40 °C, with a maximum breaking capacity of 187 kA at 240 V and 121 kA at 415 V. At 690 V the rating drops to 4.5 kA, so this breaker is sized for the 240–500 V range where the interrupting duty is highest. The continuous current holds at 250 A from 40 °C up to 50 °C, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The 86 mm depth leaves clearance for rear-connected busbars or cable lugs.
