250 A MCCB with ETU320 — selectivity and SCCR headroom
The Siemens SENTRON 3VA2325-6HL32-0AA0 is a 3-pole molded case circuit breaker rated 250 A continuous at 40 °C, carrying the same 250 A all the way to 70 °C — no derating needed across the typical panel ambient range.
Fit and footprint
The 3VA2 frame is 138 mm wide, 248 mm tall, and 110 mm deep — a standard MCCB footprint for 250 A class. Front IP40 protection means it's fine in a clean indoor panel; no washdown rating, so keep it out of wet areas.
