Its breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — numbers that tell you it's built for high-fault industrial panels, not light commercial. The 125 A rating holds steady from 40 °C up to 50 °C, then derates gradually to 112.5 A at 70 °C — so if your panel runs hot near a motor starter or drive, you still get nearly full current without nuisance tripping. The 75.6 kA interrupting rating at 240 V means it can safely clear a bolted fault up to that level, which covers most secondary-side transformer faults in industrial plants. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard MCCB footprint that drops into most SENTRON panelboards or DIN-rail adapters without re-drilling gland plates.","metaTitle":"Siemens 3VA1112-3EF32-0AB0 SENTRON MCCB, 125 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1112-3EF32-0AB0 molded case circuit breaker, 125 A continuous, 3-pole, breaking capacity 75.6 kA at 240 V.
