At 415 V and 440 V it still holds 121 kA, dropping to 75.6 kA at 500 V and 4.5 kA at 690 V. Three poles, IP40 on the front face, with a communication function onboard for integration into a monitored power system. ## Thermal derating — the real continuous current at your panel ambient Rated 250 A continuous up to 50 °C ambient. Above that, the ETU850 begins to thermally limit: 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 at 60 °C, you have 225 A available — not the full 250 A. Three-pole footprint matches standard SENTRON 3VA2 panel cutouts.","metaTitle":"Siemens 3VA2225-5KP32-0AA0 SENTRON MCCB, 250 A, 187 kA at 24","metaDescription":"Siemens 3VA2225-5KP32-0AA0 SENTRON molded case circuit breaker, 250 A continuous, 187 kA at 240 VAC.
