The 3-pole construction fits standard DIN-rail mounting in a 76.2 mm wide footprint. Rated current holds at 25 A from 40 °C through 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C — so in a warm panel you lose about 2 A of headroom. Breaking capacity steps down with voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500/690 V. ## Built-in auxiliary and release options No communication module or ground-fault monitoring is included — this is a plain line-protection device.","metaTitle":"Siemens 3VA1025-3ED32-0DC0 SENTRON MCCB, 25 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1025-3ED32-0DC0 molded case circuit breaker, 25 A rated at 40 °C, 3-pole, 75.6 kA breaking capacity at 240 V.
