The interrupting capacity at 240 V hits 220 kA, which gives serious headroom for high-fault panels; at 415 V it still holds 154 kA, and at 440 V it's 75.6 kA. The 125 A rating holds flat from 40 °C through 50 °C, then derates to 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. The 15 000 mechanical endurance cycles (latching) tell you this breaker is built for occasional switching, not daily motor-start duty. No communication function, no phase failure detection, no ground fault monitoring — this is a basic protection-only device, no bells. The auxiliary contact version is 2 auxiliary switches HQ (high-quality), which give two form-C contacts for status feedback. The integrated auxiliary trip is a separate order code (3VA9608-0BB24) — if you need a shunt trip or UVR as a field-installed accessory, that's the part number to add. No communication module, so no Modbus or PROFIBUS integration; this breaker is a standalone protection device.","metaTitle":"Siemens 3VA1112-6EF36-0CC0 SENTRON MCCB, 125 A, 3-Pole, 220","metaDescription":"Siemens 3VA1112-6EF36-0CC0 SENTRON molded case circuit breaker, 125 A rated continuous current, 3-pole, 220 kA at 240 V.
