Breaking capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, and 121 kA at 500 V — at 690 V it still holds 6 kA. That's enough SCCR headroom for most industrial distribution panels without cascading upstream breakers. This is a line-protection version (not motor-protection), meaning the trip curve and accessories are tuned for feeder and main breaker duty. At 55 °C it derates to 238 A, at 60 °C to 225 A, at 65 °C to 213 A, and at 70 °C to 200 A. If this lives in a hot enclosure — say a steel panel in a foundry or near a drive stack — that 70 °C figure is the one to plan around. Dimensions are 105 mm wide, 181 mm tall, 86 mm deep, which is the standard 3VA2 3-pole footprint. No auxiliary contacts on this variant; if you need them downstream, the base switch (3VA2225-6KP32-0AA0) is the same frame without the UVR. ## What the ETU850 trip unit gives you The ETU850 is an electronic trip unit with LSIG protection — long-time delay, short-time delay, instantaneous, and ground-fault. It's field-adjustable via the front dials, so you can coordinate selectivity downstream without swapping trip packs. ## Integration into an existing panel The 105 mm width matches the 3VA2 frame; if you're swapping out an older 3VA1 or a different brand, check the busbar pitch and lug spacing.","metaTitle":"Siemens 3VA2225-6KP32-0CA0 SENTRON MCCB, 250 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2225-6KP32-0CA0 molded case circuit breaker, 250 A rated, 242 kA breaking at 240 V, ETU850, UVR, communication.
