Its interrupting capacity hits 121 kA at 240 V and still holds 75.6 kA at 415 V — enough for high-fault panelboards and main feeder duty where selectivity with downstream breakers matters. The breaker is 76.2 mm wide, 130 mm tall, and 70 mm deep, which is the standard 3VA1112 frame footprint; it bolts into the same mounting pattern as other breakers in this series. The 125 A rating holds flat from 40 °C through 50 °C, then steps down: 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. The 76.2 mm width and 70 mm depth match the standard 3VA1112 frame — it drops into the same mounting holes and bus-bar connections as the 3VA1112-5EF32-0CA0 without rewiring. The UVR coil (order code 3VA9608-0BB25) is already installed; verify the control voltage matches your safety circuit before energizing. No auxiliary contacts are fitted on this variant, so add a separate auxiliary block if you need status feedback to a PLC.","metaTitle":"Siemens 3VA1112-4EF36-0DA0 SENTRON MCCB, 125 A, 121 kA","metaDescription":"Siemens 3VA1112-4EF36-0DA0 SENTRON molded case circuit breaker, 125 A rated continuous current, 121 kA breaking at 240 V.
