Above 55 °C the curve steps down: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. That 250 A frame holds the full rating up to 50 °C, so you don't have to oversize the breaker for a warm enclosure. Breaking capacity is the real selector here. At 240 V it clears 330 kA — that's the high-end short-circuit rating you'd expect in a main or large feeder position. At 415 V and 440 V it's still 242 kA, at 500 V it drops to 187 kA, and at 690 V it's 4.5 kA. The 690 V figure is low enough that you'd check the available fault current before putting this on a 690 V bus. ## Trip unit and communication — ETU850 with data access This breaker carries the ETU850 electronic overcurrent release, which means adjustable LSI protection (long-time, short-time, instantaneous) plus ground-fault alarm capability — the listing notes ground-fault monitoring is not built in, so that function would come from an external module if needed. The communication function is present, allowing integration with higher-level monitoring or energy management systems over the SENTRON bus or PROFIBUS/PROFINET via a communication module. Power loss is listed at a maximum of 48 W — relevant for thermal budgeting inside the enclosure, especially when multiple breakers are ganged. Dimensions are 181 mm height, 105 mm width, 86 mm depth — standard 3VA2 frame size for a 250 A unit, which means it fits the same mounting footprint as other breakers in this family.","metaTitle":"Siemens 3VA2225-7KP32-0AA0 SENTRON MCCB, 250 A, 3-Pole, ETU8","metaDescription":"Siemens 3VA2225-7KP32-0AA0 SENTRON molded case circuit breaker, 250 A rated, 3-pole, ETU850 electronic trip unit.
