The Siemens SENTRON 3VA2225-0HN32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current, designed for line protection in distribution panels and industrial switchgear. It carries a 440 kA breaking capacity at 415 V AC and 187 kA at 690 V AC, giving you serious fault-current headroom for high-capacity feeds.
Ratings that matter for fit
Rated 250 A continuous at 40 °C through 50 °C, then derates linearly to 213 A at 70 °C — so if your panel ambient runs hot, you lose about 15% capacity at the top end. The 800 V rated insulation voltage means it's comfortable on 480 V and 600 V class systems, and the 690 V operating voltage covers most industrial three-phase networks.
Dimensions: 181 mm high, 105 mm wide, 86 mm deep — fits most 3-pole MCCB footprints in existing SENTRON or third-party enclosures. No communication module, no undervoltage release, no auxiliary contacts on this order code — if you need those, you're looking at a different suffix.
