What matters for fit is the interrupting capacity: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. ## Derating and thermal management — the real-world current rating The 630 A rating holds only at 40 °C ambient. In a warm enclosure — common in food-and-beverage or furnace-adjacent panels — you must derate: 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. That heat has to leave the enclosure; plan for ventilation or a larger cabinet if the ambient runs above 40 °C. The 110 mm depth (4.33 in) is shallow enough for most 600 mm deep enclosures, but check gland-plate clearance if you are back-paneling with deep cable lugs.","metaTitle":"Siemens 3VA2463-5KP32-0BL0 SENTRON MCCB, 630 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0BL0 molded case circuit breaker, 630 A continuous, 3-pole, 187 kA at 240 V.
