The Siemens SENTRON 3VA2225-5HN32-0AA0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C, with an ETU350 electronic trip unit. What it does have is serious interrupting capacity: 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. That's built for high-fault industrial distribution panels where a line-side short can dump serious energy downstream.
Thermal derating — the real-world current rating
Above that it drops linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.
Three-pole footprint, front IP40 protection — fine for a dry indoor panel but not washdown. No communication bus; it's a standalone thermal-magnetic (electronic trip) breaker. The ETU350 trip unit is adjustable, so you set the pickup and delay per the downstream load coordination study. No auxiliary contacts or shunt trip included on this order code; if you need remote trip indication or undervoltage release, that's a different variant.
