The Siemens SENTRON 3VA2325-7MS32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It carries an ETU310M electronic overcurrent release, designed for starter protection duty, meaning it's tuned to handle motor inrush without nuisance trips while still clearing a fault fast.
This MCCB's breaking capacity climbs with system voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. At 690 V the drop to 7.5 kA reflects the physical limits of arc extinction at higher voltage; if your system runs 690 V and fault current exceeds that, you need a different frame or a current-limiting upstream device.
