That 125 A holds flat across the first three temperature steps — at 55 °C it drops to 120 A, at 60 °C to 117.5 A, at 65 °C to 115 A, and at 70 °C to 112.5 A. Breaking capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The 690 V figure of 17 kA is lower but still covers most motor-circuit fault levels at that voltage. Keep it simple. For a BOM line that needs this exact configuration — 125 A, TM210 release, UVR, 2 aux switches — the 3VA1112-5ED32-0DC0 is the correct order code. If your panel was specified around the sibling 3VA1112-5EF32-0CA0, the difference is in the release type (EF vs ED); verify the release curve matches your coordination study before substituting. The mechanical footprint — 70 mm depth, 76.2 mm width, 130 mm height — is identical across the 3VA1112 frame, so panel cutouts and busbar positions are the same. Mounts in a standard distribution panel via the SENTRON 3VA base plate or DIN rail adapter (not included). The 76.2 mm width is a 4-module footprint at 19.05 mm per module — common for Siemens switchgear. That UVR is the 3VA9608-0BB25 auxiliary trip unit, field-replaceable if it fails. Two HQ (high-quality) auxiliary switches are built in, providing status feedback for the open/closed position. No communication function, no phase failure detection, no voltage trigger — this is a pure protection device with basic signaling.","metaTitle":"Siemens 3VA1112-5ED32-0DC0 SENTRON MCCB, 125 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1112-5ED32-0DC0 molded case circuit breaker, 125 A rated current, 187 kA breaking capacity at 240 V, 3-pole, TM210 release, undervoltage release included.
