The Siemens 3VA2225-5JP32-0AH0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, holding that full rating up to 50 °C before derating starts — at 55 °C it's still good for 238 A, and at 70 °C it's 200 A. That thermal curve means you don't lose headroom in a warm panel unless ambient really climbs. Breaking capacity is 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. At 240 V that's a serious fault-current rating — enough for most North American service-entrance panels without cascading upstream.
The communication function lets it integrate into a higher-level energy monitoring system, but it's a standalone MCCB, not a power meter.
