What this 3VA2225-6HL32-0HA0 is and what it does
The Siemens SENTRON 3VA2225-6HL32-0HA0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 250 A at 40 °C, designed for line protection in distribution panels and switchboards. It carries a shunt trip release (STL) for remote tripping, and no auxiliary switch or ground-fault monitoring is fitted from the factory. 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.
What the ratings mean for your panel
The 250 A continuous rating holds flat from 40 °C through 50 °C, then derates linearly to 213 A at 70 °C. If your panel ambient runs hot — say 55 °C in a sealed enclosure — you're still good for 241 A, which is a slim 3.6% drop. That's better than many MCCBs that start derating at 40 °C. The 3-pole frame is 105 mm wide, 181 mm tall, 86 mm deep. 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.
