What this MCCB carries and where it fits
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. Its 187 kA breaking capacity at 240 V (121 kA at 415 V) means it handles high-fault-current industrial feeds without cascading upstream — sized for main or large feeder duty in a distribution panel. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint for DIN-rail or panel-mount integration. The front face carries IP40 protection, adequate for enclosed panel environments.
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. If your panel ambient runs above 50 °C, size the breaker for the derated current — the 250 A nameplate applies only up to that point. Rated insulation voltage is 800 V, and the maximum power loss is 48 W — a figure to consider for thermal budgeting inside a sealed enclosure.
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.
