That steep fall-off above 440 V is the key selection constraint — if your system fault current at 690 V exceeds 7.5 kA, this breaker won't clear it, and you need a higher-rated frame or upstream current-limiting fuse. Full rated current holds at 63 A up through 50 °C ambient. At 55 °C it derates to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. In a sealed, tightly packed panel that runs hot, that derating curve is your real-world ampacity — don't size the load to 63 A if the enclosure ambient is over 50 °C. That 76.2 mm (3-inch) width is the standard 3-pole MCCB footprint — it drops into the same DIN-rail or panel-mount slot as other SENTRON 3VA frames of this size class.","metaTitle":"Siemens 3VA1163-5MH32-0AA0 SENTRON MCCB, 63 A, 3-Pole, TM120","metaDescription":"Siemens SENTRON 3VA1163-5MH32-0AA0 molded case circuit breaker, 63 A at 40 °C, 3-pole, TM120M thermal-magnetic release, 187 kA at 240 V.
