If your panel ambient runs 50 °C, the usable current is 593 A, not the nameplate 630 A. The interrupting ratings span 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V — the 690 V figure drops sharply because arc extinction physics changes at that voltage. This is a line-protection design (not motor-protection), so it is intended for feeder and distribution duty, not direct motor starting. The failure mode to watch is thermal accumulation at the terminals under sustained high load. With a maximum power loss of 162 W, the breaker dissipates heat into the enclosure. Plan the gland plate and ventilation accordingly — the 110 mm depth, 138 mm width, and 248 mm height give you the envelope for DIN-rail or screw-mount integration. The basic switch variant is listed as 3VA2463-7HN32-0AA0 — the -0AC0 suffix indicates the auxiliary switch configuration: two auxiliary switches (HQ type) are fitted. If your spec requires those, this is the clean base variant. Three-pole design, 110 mm deep × 138 mm wide × 248 mm tall. The width is the critical panel cutout dimension — 138 mm is standard for a 630 A frame MCCB in the SENTRON 3VA series. Verify the DIN-rail or screw-mount pattern against your existing backplate; the 3VA2463 frame shares the same footprint as other 630 A SENTRON breakers, so a panel cut for a 3VA2163-8HM32-0AA0 will accept this unit without rewiring.","metaTitle":"Siemens 3VA2463-7HN32-0AC0 SENTRON MCCB, 630 A, 3-pole","metaDescription":"Siemens SENTRON 3VA2463-7HN32-0AC0 molded case circuit breaker, 630 A continuous, 3-pole, 330 kA at 240 V.
