The 110 mm depth and 138 mm width keep it within a standard MCCB footprint, so it swaps into existing SENTRON switchboard layouts without re-drilling gland plates. Rated 630 A at 40 °C, it derates to 520 A at 70 °C — that's about 17 % loss across the full ambient span. ## Trip unit and auxiliary contacts The integrated auxiliary trip is order code 3VA9608-0BB11 if you need to add a shunt or undervoltage release later. Breaking capacity drops from 242 kA at 240 V to 40 kA at 690 V — still a strong number for a 630 A frame at the higher voltage. At 415 V and 440 V it holds 187 kA, at 500 V it's 121 kA. That covers most industrial low-voltage networks without needing a current-limiting upstream breaker.","metaTitle":"Siemens 3VA2463-6HN32-0AF0 SENTRON MCCB, 630 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0AF0 molded case circuit breaker, 630 A at 40 °C, 3-pole, ETU350 trip unit, 242 kA at 240 V.
