The 250 A rating holds up to 50 °C ambient. Above that, derate: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. If your panel runs hot — near a drive cabinet or in a non-climate-controlled enclosure — the 60 °C or 65 °C figure is the one you size the load against, not the 40 °C number. No undervoltage release or voltage trigger on this variant, but the communication function is present. The 3VA2116-5HM42-0CC0 is a smaller-frame 3VA1 series breaker — lower current rating, different trip unit, and a 3-pole design. The 3VA2225-5KQ42-0AA0 is a 4-pole, 250 A frame with the ETU860 electronic trip; it will not drop into a panel wired for the 3VA1 without a busbar rework and likely a larger enclosure cutout. If you're replacing a 3VA1 in the field, check the mounting footprint first — the 3VA2 frame is physically larger.","metaTitle":"Siemens 3VA2225-5KQ42-0AA0 SENTRON MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5KQ42-0AA0 molded case circuit breaker, 250 A, 4-pole, 187 kA at 240 V.
