For DC applications, the rated operational voltage is 500 V. The TM240 release means the thermal element is calibrated for a 240 A frame — this breaker is the 25 A tap, so the trip curve is fixed and non-interchangeable in the field. ## Panel Integration Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. Power loss is 8.5 W maximum, so thermal rise inside a sealed cabinet is manageable but should be factored into the cooling budget.","metaTitle":"Siemens 3VA1125-6EF32-0AA0 SENTRON MCCB, 25A, 220kA at 240V","metaDescription":"Siemens SENTRON 3VA1125-6EF32-0AA0 molded case circuit breaker, 3-pole, 25A, TM240 release, 220 kA at 240 V AC.

The key difference is the current rating: 25 A on this unit versus the lower-rated 3VA1110-5ED32-0AA0. Verify the load and trip coordination before swapping — the TM240 release is the same frame, so the breaker's interrupting capacity at the applied voltage must also be checked."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1125-6EF32-0AA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1125-6EF32-0AA0 when reusing this data.
