Its headline breaking capacity hits 220 kA at 240 V, tapering to 154 kA at 415 V and 121 kA at 440 V — numbers that tell you this breaker is built for high-fault locations like utility tie-ins or large transformer secondaries where available fault current is serious. ## Dimensional check for panel swap At 70 mm deep, 76.2 mm wide, and 130 mm tall, this breaker occupies the same 3VA frame as the 3VA1110 and 3VA1112 siblings. If you're replacing a 3VA1110-5EF32-0AM0 or 3VA1112-5EE32-0AA0, the mounting hole pattern and bus-bar spacing are identical — no rewiring of the panel backplate. The auxiliary switch configuration (2 HQ auxiliary switches) is factory-fitted; verify that the existing control wiring matches the HQ contact arrangement before committing the swap.","metaTitle":"Siemens 3VA1125-6EF32-0AC0 SENTRON MCCB, 25 A, 220 kA at 240","metaDescription":"Siemens 3VA1125-6EF32-0AC0 SENTRON molded case circuit breaker, 3-pole, 25 A, TM240 release, 220 kA at 240 V.

Availability and current pricing are confirmed at quote time — no stock count or lead-time number is published here. The part is sourced through independent distribution channels."},{"question":"Will 3VA1125-6EF32-0AC0 drop into a panel built for 3VA1110-5EF32-0AM0?","answer":"Yes. All three share the same 3VA frame dimensions — 70 mm deep, 76.2 mm wide, 130 mm tall — so the mounting hole pattern and bus-bar spacing are identical. No backplate modification needed. Verify the auxiliary switch wiring matches the HQ contact arrangement before the swap."},{"question":"What is the breaking capacity of this MCCB at different voltages?","answer":"220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. The high 240 V figure suits transformer secondary or utility tie-in applications where available fault current is extreme."},{"question":"What compliance documentation does Siemens provide for this part?","answer":"The evidence does not list specific compliance certificates (RoHS, REACH, UL, IEC) for this order code.
