The 220 kA at 240 V is the headline number, but the full SCCR curve matters for coordination studies: 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. At 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in), it fits the same cutout as other 3VA 3-pole frames. The shunt trip (STL) auxiliary release is built in — no external relay needed for remote tripping. The 25 A rating holds flat from 40 °C to 50 °C, then derates to 24 A at 55 °C and 60 °C, and 23 A at 65 °C and 70 °C.","metaTitle":"Siemens 3VA1125-6EF32-0JA0 SENTRON MCCB, 25A, 220kA at 240V","metaDescription":"Siemens SENTRON 3VA1125-6EF32-0JA0 molded case circuit breaker, 3-pole, 25A rated at 40°C, 220kA breaking capacity at 240V AC, with TM240 thermal-magnetic release and shunt trip.
