Breaking capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V and 3 kA at 690 V. The 3 kA at 690 V is the ceiling; if your system runs 690 V line-to-line, verify the prospective fault current stays under that. Rated insulation voltage is 800 V, operating voltage 690 V AC — so the breaker is electrically rated for 690 V line work, but the interrupting capability at that voltage is limited. ## Panel fit and physical integration Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. Three-pole footprint matches standard MCCB spacing; no special bus adapter needed for most SENTRON distribution blocks. Power loss is 0.84 W max — negligible for thermal budgeting inside a sealed enclosure, but if you're packing multiple breakers in a small cabinet, sum the losses and check the temperature rise against the 70 °C operating max.","metaTitle":"Siemens 3VA2025-5HN36-0AA0 SENTRON MCCB, 25 A, 3-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2025-5HN36-0AA0 molded case circuit breaker, 25 A continuous, 3-pole, ETU350 release.
