The breaker's interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V, and 121 kA at 500 V — high enough for most main feeder applications, though it drops to 4.5 kA at 690 V, so watch the voltage class in your system.
The 250 A continuous rating holds flat from 40 °C through 50 °C, then derates linearly to 213 A at 70 °C. That's better than many MCCBs that start derating at 40 °C. It's a standard SENTRON 3VA2 footprint, so it bolts into existing 3VA2 mounting plates and busbar kits without re-drilling. No communication module, no trip indicator — this is a straightforward thermal-magnetic line-protection breaker with a shunt trip for emergency off or remote disconnect.
