This is the line-protection variant — no voltage trip, no phase-failure detection, no communication module. Front protection is IP40 — splash-safe in the cabinet but not washdown-rated. The TM240 release holds full 125 A up to 50 °C, then derates to 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. At 415 V (common in European industrial panels), 154 kA still covers most utility-transformer fault levels. If the BOM needs adjustable overloads or a higher amp frame, look at the 5EF or 5EE siblings in the same 3VA1112 envelope.","metaTitle":"Siemens 3VA1112-6EF32-0DH0 SENTRON MCCB, 125A, 220kA at 240V","metaDescription":"Siemens 3VA1112-6EF32-0DH0 SENTRON 3-pole molded case circuit breaker, 125 A rated current, 220 kA breaking capacity at 240 V AC.
