This breaker has no communication function, no undervoltage release, and no voltage trip — it is a straightforward, non-communicating thermal-magnetic replacement with an electronic trip curve. ## Breaking capacity — the real-world fault clearing muscle This MCCB delivers 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. Those are very high interrupting ratings — typical for a large-frame, high-end SENTRON 3VA2. ## Thermal derating — what happens when the panel runs hot At 55 °C it derates to 241 A, at 60 °C to 232 A, at 65 °C to 222 A, and at 70 °C to 213 A. If your panel ambient sits above 50 °C — common in a packed enclosure or near a heat source — factor that derating into the feeder sizing. That is not trivial in a sealed enclosure; account for it in the thermal budget if the breaker is in a confined space with other heat-generating components.","metaTitle":"Siemens 3VA2225-8HL32-0AA0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2225-8HL32-0AA0 SENTRON molded case circuit breaker, 250 A continuous, 3-pole, ETU320 release, 440 kA at 240 V.
