The 415 V operating voltage sees a 9 kA interrupting rating, so the application voltage determines which rating governs your SCCR coordination study. Rated 25 A from 40 °C through 50 °C, then steps down to 24 A at 55 °C and 60 °C, and 23 A at 65 °C and 70 °C. If your enclosure ambient sits above 50 °C, you lose 1–2 A of headroom — factor that into the load schedule. The 25.4 mm width (1 inch) and 70 mm depth let it snap onto standard DIN rail; the 130 mm height keeps it within a typical distribution panel's gland-plate clearance. This part is in active current production. The SENTRON 3VA series is Siemens' standard MCCB line.","metaTitle":"Siemens 3VA1125-4ED12-0AA0 SENTRON MCCB, 1-pole, 25 A, 240 V","metaDescription":"Siemens SENTRON 3VA1125-4ED12-0AA0 molded case circuit breaker, 1-pole, 25 A rated at 40 °C, 240 V interrupting rating 75.6 kA.
