That steady thermal curve means you don't lose headroom in a warm enclosure unless the ambient pushes past 50 °C. The interrupting ratings tell the real story for fault coordination: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. At 690 V the 4.5 kA figure is modest, so if your line side is 690 V with high available fault current, you'll want to check the coordination study. You set the curves to match your load, which is the difference between protecting a feeder and nuisance-tripping on a motor inrush. ## Sourcing and lifecycle — still in current production The 3VA2225-5HN42-0BA0 is the line-protection variant with an undervoltage release and no auxiliary contacts. If your panel callout requires auxiliary signaling or a different trip-unit firmware, the 3VA2225-5HN42-0BB0 is the closest sibling — same frame, same 250 A rating, same ETU350, but with auxiliary contact provision. The footprint and wiring are identical; the swap is a terminal-level decision, not a panel rework. ## Mounting and integration — fits the standard footprint Four-pole, so it needs the full 140 mm width on the DIN-rail or mounting plate. The undervoltage release is fitted as standard — if your control scheme doesn't use it, you'll need to wire it continuously energized or order the variant without it.","metaTitle":"Siemens 3VA2225-5HN42-0BA0 SENTRON MCCB, 250 A, 4-Pole, 187","metaDescription":"Siemens 3VA2225-5HN42-0BA0 SENTRON molded case circuit breaker, 250 A continuous, 4-pole, ETU350 release, 187 kA at 240 V.
