At 240 V it interrupts 220 kA; at 415 V it handles 154 kA; at 440 V it drops to 75.6 kA; at 500 V and 690 V it holds at 17 kA. At 690 V the 17 kA figure is modest; verify your transformer's secondary fault current if using this breaker on a 690 V line. ## Thermal derating — the 125 A rating is not flat across temperature The 125 A rating holds from 40 °C through 50 °C, then begins to step down: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. ## Physical fit and auxiliary configuration Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or panel-mount installation. The basic switch order code is 3VA11126EF320AA0, which is the core switching mechanism; the -0AG0 suffix adds the specific factory-installed accessories.","metaTitle":"Siemens 3VA1112-6EF32-0AG0 SENTRON MCCB, 125 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1112-6EF32-0AG0 SENTRON molded case circuit breaker, 125 A rated at 40 °C, 3-pole, TM240 thermal-magnetic release, 220 kA at 240 V.

The difference is the overcurrent release: this unit uses a TM240 thermal-magnetic release, while the -5EE32-0AA0 uses a different release variant. Verify that the TM240's trip curve matches your coordination study before swapping — the breaker body and mounting are the same, but the protection settings differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-6EF32-0AG0","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/3VA1112-6EF32-0AG0 when reusing this data.
