This matters for panel builders stuffing a hot enclosure — the 250 A nameplate holds only if the air around the breaker stays at or below 50 °C. ## Auxiliaries and releases — what comes built in The basic switch assembly is order code 3VA2225-5HN32-0AA0, meaning the auxiliaries and UVR are integrated at the factory, not field-added. If you need a different aux configuration, you're looking at a different base variant. A mechanical trip indicator is present — useful for remote status without opening the panel door. That depth is the key number for enclosure selection — 86 mm (3.39 in) means it fits standard shallow distribution boards, but check gland-plate clearance if you're mounting a deep rotary handle. Maximum power loss is 50.5 W at rated load — not negligible in a sealed enclosure; factor it into your thermal budget if the panel is NEMA 4X or IP65.","metaTitle":"Siemens 3VA2225-5HN32-0DH0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5HN32-0DH0 molded case circuit breaker, 250 A continuous, 3-pole, 187 kA interrupting at 240 V.
