Breaking capacity varies sharply with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. At typical 400 V class industrial feeds, the 121 kA figure gives substantial headroom above most transformer secondary fault currents, so you can usually skip current-limiting fuses upstream. Rated insulation voltage is 800 V, and the breaker holds its full 25 A rating across the entire operating temperature range from -25 °C to 70 °C — no derating needed even in a warm enclosure. Power dissipation is a modest 0.84 W at rated load. Dimensions are 181 mm high, 140 mm wide, 86 mm deep. The 140 mm width is standard for a 4-pole MCCB in this frame size — it occupies the same footprint as other SENTRON 3VA breakers in the same rating class, so a panel laid out for a 3VA2 frame accepts this unit without re-drilling the mounting plate or changing busbar drop distances.","metaTitle":"Siemens 3VA2025-5HN46-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2025-5HN46-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, ETU350 trip unit.
