The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V — figures that govern selectivity and SCCR headroom in the distribution panel. ## Thermal Derating and Ambient Constraints The 250 A rating holds up to 50 °C ambient. Above that, the continuous current must be derated: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. Maximum power loss is 50.5 W, which factors into enclosure thermal management for a panel builder. ## Auxiliary and Communication Capabilities The integrated auxiliary trip module is order code 3VA9608-0BB11; the basic switch is 3VA2225-5KP32-0AA0. A trip indicator is present for visual fault confirmation. Verify the gland-plate cutout and phase-spacing against the existing panel layout before wiring.","metaTitle":"Siemens 3VA2225-5KP32-0BH0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5KP32-0BH0 molded case circuit breaker, 250 A, 3-pole, 187 kA at 240 V.
