That 76.2 mm width is a standard 3-pole MCCB footprint — three 25.4 mm pole centers. Front protection is IP40 (finger-safe, no water ingress). No communication function, no phase failure detection, no ground fault monitoring on this version.","metaTitle":"Siemens 3VA1112-5ED32-0CA0 SENTRON MCCB, 125 A, TM210","metaDescription":"Siemens SENTRON 3VA1112-5ED32-0CA0 molded case circuit breaker, 125 A rated continuous current, TM210 thermal-magnetic release, 187 kA at 240 V.

The key difference is the trip unit: the -5ED32-0CA0 carries a TM210 thermal-magnetic release, while the -5EF32-0CA0 uses a different trip curve or electronic release. Physically they share the same 3-pole footprint and mounting pattern, so panel fit is identical — but the trip coordination changes. Verify the trip curve matches your selective coordination study before swapping."},{"question":"What is 3VA1112-5ED32-0CA0's listed depth?","answer":"The listed depth is 70 mm."},{"question":"What is 3VA1112-5ED32-0CA0's listed width?","answer":"The listed width is 76.2 mm — standard 3-pole MCCB width at 25.4 mm per pole."},{"question":"Will 3VA1112-5ED32-0CA0 drop into a panel specified around 3VA1112-5EF32-0CA0 without rewiring?","answer":"Yes, same 3-pole frame, same mounting dimensions (130 mm height, 76.2 mm width, 70 mm depth). The physical fit is identical — no rewiring needed for the panel cutout or bus connection. The difference is in the trip unit; the TM210 thermal-magnetic release on this variant may have a different time-current curve than the -5EF32 variant, so verify coordination study compatibility before swapping."},{"question":"What compliance documentation does Siemens provide for 3VA1112-5ED32-0CA0?","answer":"As a SENTRON molded case circuit breaker, it carries the standard IEC/EN 60947-2 certifications for the class.
