Thermal derating is published across the full range: 630 A at 40 °C drops to 520 A at 70 °C, so a warm panel environment costs you about 17 % of the rating. The breaker dissipates 164.5 W max, which needs to be factored into enclosure ventilation for a closed-door installation (–,). ## Interrupting capacity and selectivity headroom The 3-pole form factor fits standard MCCB mounting patterns in switchgear. The auxiliary switch complement includes two auxiliary switches plus a trip alarm and an electrical alarm switch (HQ type), which covers remote status feedback without an add-on module. Dimensions: 110 mm deep, 138 mm wide, 248 mm tall. That width is standard for a 630 A frame — verify panel cutout and busbar spacing against the existing switchgear layout.","metaTitle":"Siemens SENTRON 3VA2463-6HN32-0BL0 MCCB, 630 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0BL0 molded case circuit breaker, 630 A continuous, 3-pole, 242 kA interrupting at 240 V.
