The thermal derating curve is flat from 40 °C to 50 °C at 25 A, then steps down to 24 A at 55 °C and 60 °C, and 23 A at 65 °C and 70 °C. No communication module is fitted, and there is no ground-fault monitoring or N-conductor protection built in. The 101.6 mm width (4 inches) is the standard footprint for a 4-pole SENTRON 3VA frame at this rating — it occupies the same DIN-rail or mounting-plate space as other 4-pole 3VA breakers in the same frame size. If you're replacing a 3VA1020-3ED36-0AA0 or similar, the physical envelope is identical; no panel re-drilling or bus-bar rework is required. With 121 kA at 240 V and 75.6 kA at 415 V, this breaker is sized for high-fault-current installations — typically a main or feeder position in an industrial distribution board where the available fault current exceeds what a standard MCB can handle. The TM210 release provides thermal protection for overloads and magnetic (instantaneous) protection for short circuits. For DC applications, the maximum rated operational voltage is 600 V; the manufacturer's device manual covers specific DC switching power values and should be consulted for DC coordination studies.","metaTitle":"Siemens 3VA1025-4ED46-0AA0 MCCB, 25 A, 4-Pole, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1025-4ED46-0AA0 molded case circuit breaker, 25 A, 4-pole, 121 kA at 240 V.
