That SCCR range means this breaker can sit ahead of a step-down transformer or a high-fault panel without cascading upstream — it safely clears a bolted fault at those levels. The 2 auxiliary switches are integral — no external wiring for the status contacts needed. Verify the TM240 release curve coordinates with downstream breakers for selective tripping.","metaTitle":"Siemens 3VA1110-5EF32-0AB0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens 3VA1110-5EF32-0AB0 SENTRON MCCB, 100 A continuous, 3-pole, TM240 release.

The key difference is the overcurrent release: the -5EF32-0AB0 uses a TM240 release; the -5EE32-0DC0 uses a different trip unit. Both are 3-pole, 100 A, same footprint — the swap depends on whether the trip curve matches your coordination study."},{"question":"What is the depth of 3VA1110-5EF32-0AB0?","answer":"70 mm."},{"question":"What is the width of 3VA1110-5EF32-0AB0?","answer":"76.2 mm."},{"question":"Will 3VA1110-5EF32-0AB0 drop into a panel specified for 3VA1110-5EE32-0DC0 without rewiring?","answer":"Yes — both are the same 3-pole 100 A frame with identical mounting dimensions (76.2 mm wide, 130 mm tall, 70 mm deep). The auxiliary contact count matches (2 auxiliary switches HP). The only difference is the overcurrent release design; if the trip curve is acceptable, the swap is mechanical."},{"question":"What compliance documentation does Siemens provide for 3VA1110-5EF32-0AB0?","answer":"The product is designed to meet IEC/EN 60947-2 for MCCBs.
