The 630 A rating is at 40 °C ambient; above that you derate linearly — 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. The depth of 110 mm means it clears most 200 mm-deep enclosures with room for rear-connected busbars or a shunt trip (STL) wired behind the base. No communication module or ground-fault monitoring on this order code. If you need remote trip indication or GF protection, you step up to the 3VA2 with electronic trip units and communication options. Maximum power loss is 162 W at full rated current — that heat has to leave the enclosure. If you're retrofitting into a panel originally built for a 5SQ2370-2YA05 frame, check the mounting footprint and busbar centers; the SENTRON 3VA series uses a different bolt pattern than the older 5SQ generation, so a direct drop-in without drilling or a busbar adapter is unlikely.","metaTitle":"Siemens 3VA2463-5HN32-0HH0 SENTRON MCCB, 630A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2463-5HN32-0HH0 molded case circuit breaker, 630A continuous, 3-pole, 187kA interrupting at 240V.
