Three poles, line-protection version, no undervoltage release, no ground-fault module, no communication stack — it's a straight feeder or main breaker, not a multifunction device. ## Thermal derating and real-world loading At 40 °C the breaker holds the full 250 A without derating; at 55 °C it's 241 A, at 70 °C it's 213 A. That means in a warm panel — say 50 °C — you still get the full 250 A, but if the enclosure runs hot from adjacent drives or transformers, you lose about 15 % by 70 °C. Plan your ambient accordingly. Maximum power loss is 48 W at rated current — not trivial in a sealed enclosure. ## Footprint and mounting ## Auxiliary contact configuration","metaTitle":"Siemens 3VA2225-6HN32-0AJ0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2225-6HN32-0AJ0 molded case circuit breaker, 250 A rated, 3-pole, ETU350 trip unit.
