The Siemens SENTRON 3VA2325-0HM32-0AA0 is a 3-pole molded case circuit breaker rated 250 A continuous at 40 °C through 70 °C — no derating needed across that band, which simplifies panel thermal budgeting. The ETU330 electronic trip unit gives adjustable long-time pickup (50–250 A) and instantaneous pickup up to 3000 A, plus ground-fault summation sensing on the L-conductor. Front IP40 protects against tool entry, but the body is not sealed for washdown.
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — standard 3-pole MCCB footprint for a 250 A frame. Compliance documentation (RoHS, REACH, IEC/UL) is provided with the unit; the brand supplies a declaration of conformity on request.
