What sets this MCCB apart is the flat derating curve: the 63 A rating holds from 40 °C through 70 °C ambient, with no reduction at 65 °C or 70 °C. That means in a tightly packed enclosure or near heat sources, you don't lose ampacity — the breaker delivers its full 63 A across the operating range of -25 °C to 70 °C. Physical footprint is 86 mm depth by 105 mm width by 181 mm height (3.39 x 4.13 x 7.13 inches). The 105 mm width for a 3-pole MCCB is standard for Siemens SENTRON frames — it occupies three modular 35 mm DIN spaces, so it drops into existing SENTRON panel layouts without re-drilling gland plates or re-spacing busbars.","metaTitle":"Siemens 3VA2163-8KQ32-0AA0 SENTRON MCCB, 63 A, 3-Pole, 440 k","metaDescription":"Siemens SENTRON 3VA2163-8KQ32-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, 440 kA at 240 V.
