The 25 A rating holds flat from 40 °C to 50 °C, then derates gently to 23 A at 70 °C — no surprise derating curve for a panel that runs warm. Power loss maxes at 8.5 W; four poles dissipating that in a sealed enclosure needs a thermal check, but in a ventilated panel it's fine. Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — a 4-pole frame that fits standard Siemens 3VA mounting footprints.","metaTitle":"Siemens 3VA1025-3ED42-0AA0 SENTRON MCCB, 25 A, 4-Pole, 75.6","metaDescription":"Siemens 3VA1025-3ED42-0AA0 SENTRON molded case circuit breaker, 25 A rated at 40 °C, 4-pole, 75.6 kA interrupting at 240 V.
