At 240 V this breaker clears 121 kA symmetrical; at 415 V it's 75.6 kA, at 440 V it's 52.5 kA, and at 690 V it's 11.9 kA. That's a steep voltage-dependent drop — if your panel feeds a 690 V motor circuit, the available fault current must stay under 11.9 kA or you need a higher-rated frame. The 25 A rating holds flat from 40 °C to 50 °C, then derates to 24 A at 55 °C and 22.5 A at 70 °C. In a hot enclosure near the top of a panel, that 70 °C figure governs the actual load you can protect. The shunt trip (STL) is the only integrated auxiliary release, so if you need undervoltage release or ground fault monitoring, this variant does not carry them.","metaTitle":"Siemens 3VA1025-4ED32-0JA0 SENTRON MCCB, 25 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1025-4ED32-0JA0 molded case circuit breaker, 25 A rated, 121 kA breaking at 240 V. 3-pole, TM210 release, shunt trip.
