Only at 690 V does it drop to 3 kA, so if you're on a 690 V system, this is not your breaker. ## Physical fit and mounting The 3VA2025-7HN32-0AA0 measures 105 mm wide by 181 mm tall by 86 mm deep. It's a standard MCCB footprint for this class, so it swaps into existing SENTRON panelboards or DIN-rail adapters without re-drilling. ## Thermal performance and environment Rated current holds at 25 A across the full ambient temperature range from 40 °C up to 70 °C — no derating needed in a hot panel. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. Insulation voltage is rated at 800 V, giving margin above the 600 V class systems this breaker typically serves. Power loss is minimal at 0.5 W maximum, so heat buildup in a dense panel is negligible.","metaTitle":"Siemens 3VA2025-7HN32-0AA0 SENTRON MCCB, 25 A, 3-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2025-7HN32-0AA0 molded case circuit breaker. 25 A continuous, 3-pole, ETU350 trip unit. 330 kA at 240 V.
