Its continuous current rating holds at 63 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that temperature, which simplifies panel layout in warm enclosures. The interrupting ratings tell you where this breaker can safely clear a fault: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. That 440 kA at 240 V is the headline number — it handles the high available fault current you get close to a large transformer or a utility service entrance. The 52.5 kA at 690 V still covers most industrial 690 V distribution without needing a current-limiting fuse upstream. The ETU350 electronic trip unit gives you adjustable overload and short-circuit protection curves, which is what you want for coordinating with downstream breakers in a selective system. Insulation voltage is rated 800 V, so the breaker is suitable for 690 V line-to-line systems with margin. ## Physical fit and panel integration Dimensions are 140 mm wide, 181 mm high, and 86 mm deep. The 140 mm width for a 4-pole frame is standard for SENTRON 3VA2 breakers — it will drop into the same mounting footprint as other 3VA2 4-pole units. Front protection is IP40, meaning tools and fingers stay out, but it is not sealed against washdown; keep it inside the enclosure.","metaTitle":"Siemens 3VA2163-8HN42-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2163-8HN42-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, ETU350 trip unit, 440 kA at 240 V.
