The 630 A rating holds only at 40 °C ambient. Above that, derate linearly: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. In a sealed, high-ambient panel — say a 50 °C switchroom — the usable current drops to 570 A, so size your bus and cable accordingly. Maximum power loss is 164.5 W, which contributes to the enclosure thermal budget; factor that into the ventilation or forced-air calculation for a multi-breaker lineup. Physical dimensions are 110 mm depth, 138 mm width, and 248 mm height. The 138 mm width for a 3-pole 630 A frame is standard for this class — it occupies roughly 5.4 inches of DIN-rail space. The depth of 110 mm (4.33 in) means it clears most 200 mm deep enclosures, but verify gland-plate clearance if the line-side lugs protrude rearward. ## Auxiliary switch complement and UVR — pre-configured for safety circuits That means it arrives ready for remote trip indication and undervoltage protection without adding separate accessory modules. The basic switch variant is 3VA2463-6KP32-0AA0; this -0BL0 suffix adds the full complement of switches and the UVR. No ground-fault monitoring version is included — this is a line-protection breaker without integral GFCI. If ground-fault detection is needed downstream, add an external relay or specify the GF variant.","metaTitle":"Siemens 3VA2463-6KP32-0BL0 SENTRON MCCB, 630 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2463-6KP32-0BL0 molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, 187 kA breaking at 415 V.
