The Siemens 3VA2325-6HN32-0HL0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous at 40 °C through 70 °C, with a 3-pole configuration and an interrupting capacity of 242 kA at 240 V. This is a line-protection design — meaning it's built for feeder and main breaker duty in distribution panels, not motor-starting applications. The 250 A rating holds flat across the full ambient range, so no derating curve to manage in a warm enclosure.
Compared to the 3VA2225-5HN42-0BB0, the 3VA2325-6HN32-0HL0 carries the same 250 A frame but with a higher interrupting rating — 242 kA vs the 3VA2225's 200 kA at 240 V. The 3VA2325 also includes the shunt trip (STL) release and the full auxiliary switch complement (2 aux + 1 trip alarm + 1 electrical alarm), where the 3VA2225-5HN42-0BB0 may come with a different accessory configuration. If your panel was wired around the 3VA2225, the 3VA2325 drops into the same footprint — same 138 mm width, 110 mm depth, 248 mm height — but verify the shunt trip wiring if the original spec didn't call for one.
Panel integration: the 3VA2325-6HN32-0HL0 mounts on a DIN rail or direct panel-mount via the 138 mm width footprint. The 110 mm depth fits standard distribution board depths. The shunt trip (STL) release is factory-installed — no field retrofit. Auxiliary switches are pre-configured: 2 aux + 1 trip alarm + 1 electrical alarm. No communication function onboard; this is a standalone breaker. Power loss at full load is 37.5 W — account for that heat in the enclosure thermal calculation.
