The interrupting ratings tell you where it fits: 121 kA at 240 V AC, 75.6 kA at 415 V and 440 V, 52.5 kA at 500 V, and 4.5 kA at 690 V. At 690 V the 4.5 kA figure is lower, but that's typical for a 250 A frame at that voltage; the real-world application is usually 400–480 V where you've got plenty of headroom. Above that it starts to taper: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. That's a straight linear derate of about 1.8 A per degree past 50 °C. The operating range tops out at 70 °C ambient; storage can take -40 °C to 80 °C. ## Physical fit — panel integration notes The 105 mm width is three-pole standard for this SENTRON frame; if you're swapping into an existing cutout that was sized for a different 250 A MCCB, measure the width first because some older frames are wider.","metaTitle":"Siemens 3VA2225-4HM32-0AA0 SENTRON MCCB, 250 A, 121 kA at 24","metaDescription":"Siemens SENTRON 3VA2225-4HM32-0AA0 molded case circuit breaker, 3-pole, 250 A, 121 kA at 240 V AC.
