The Siemens SENTRON 3VA2325-6HL32-0AJ0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current across its full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity runs 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. That spread tells you this breaker is built for high-fault industrial distribution where the available short-circuit current is substantial at lower voltages.
What the ratings mean for fit
The 250 A rating holds flat from 40 °C to 70 °C ambient, so you don't have to oversize for a warm panel. Power loss is 37.5 W maximum — relevant for enclosure thermal calculations when grouping several breakers. The breaker carries a trip indicator and comes with 2 auxiliary switches plus 1 trip alarm switch (HP design), which simplifies status feedback to a PLC or annunciator without adding separate contact blocks.
Panel integration
Dimensions are 248 mm high, 138 mm wide, 110 mm deep. Mounts on a standard DIN rail or with screw-mount lugs. The 3-pole footprint fits a typical MCCB slot in a distribution panel; the 110 mm depth leaves clearance behind a 200 mm deep enclosure door.
