That 125 A holds flat across the 40–50 °C band — no derate needed in a warm panel — then steps down to 122 A at 55 °C and 114 A at 70 °C. Interrupting capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. Dimensions: 130 mm tall, 101.6 mm wide, 70 mm deep. Four-pole width at 101.6 mm (4 inches) matches standard MCCB spacing. Max power loss is 28.1 W. In a sealed panel with multiple breakers ganged, that heat adds up — plan for ventilation or derate if ambient inside the enclosure pushes past 50 °C. The 70 °C operating ceiling matches the derate curve top end. ## What it doesn't carry This is a straight thermal-magnetic breaker — no aux electronics. If you need shunt trip or remote status, you're looking at a different variant in the 3VA family.","metaTitle":"Siemens 3VA1112-6EF42-0AA0 SENTRON MCCB, 4-Pole, 125 A, 220","metaDescription":"Siemens 3VA1112-6EF42-0AA0 SENTRON 4-pole molded case circuit breaker, 125 A continuous, 220 kA interrupting at 240 V.
