Breaking capacity is the headline: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 76 kA at 500 V, and 4.5 kA at 690 V. That 187 kA figure at 240 V means this breaker handles high-fault-current scenarios common in North American 240/120 V split-phase or 240 V delta services without needing a current-limiting fuse upstream. At 415/440 V — typical European industrial voltages — the 121 kA rating still covers most utility transformer secondary faults. The drop to 4.5 kA at 690 V tells you this is not the breaker for 690 V high-fault installations; for those, step up to the 3VA2 high-capacity variant. Rated 250 A continuous up to 50 °C ambient. Above that, derate linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C. If your panel ambient runs 60 °C, you lose 18 A of headroom — factor that into the load schedule. The 86 mm depth, 140 mm width, and 181 mm height fit the standard 3VA2 cutout; no special adapter plate needed for most enclosure backpanels. Maximum power loss is 48 W. For a panel with multiple breakers at full load, sum the losses and size the ventilation or air conditioning accordingly — 48 W per breaker adds up fast in a multi-feeder lineup.","metaTitle":"Siemens 3VA2225-5HN42-0KB0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2225-5HN42-0KB0 SENTRON molded case circuit breaker, 250 A rated current, 4-pole, ETU350 release, breaking capacity up to 187 kA at 240 V.
