The Siemens SENTRON 3VA2225-5HL32-0HA0 is a 3-pole molded case circuit breaker (MCCB) rated 250 A at 40 °C, with the ETU320 electronic trip unit for line protection.
Ratings that govern the real load
The 250 A rating holds flat from 40 °C to 50 °C, then derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.
What is not on this variant
This version ships without auxiliary contacts, without an undervoltage release, without ground-fault monitoring, and without communication functions. The trip indicator is also absent. If any of those are required for your circuit, the base switch order code is 3VA2225-5HL32-0AA0, and you would add the needed modules separately.
