The 3VA2225-0HL32-0AA0 is a SENTRON 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C through 50 °C, then derating to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C — so if your panel ambient runs above 50 °C, the breaker's effective capacity drops, and you size the load accordingly.
The IP40 front protection means it's suitable for indoor switchgear but not washdown areas; keep it in a dry, dust-controlled cabinet. Maximum power loss is 48 W — account for that heat in your enclosure's thermal budget, especially when multiple breakers are ganged.
No official successor has been assigned; the 3VA2 platform remains active. For BOM freeze or long-term planning, the ETU320 trip unit and 250 A frame are standard catalog items with broad channel support.
