The interrupting capacity (Icu) hits 187 kA at 240 VAC, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 9 kA at 690 V — so the voltage class of your distribution system drives which fault level this breaker can clear. The continuous current rating is 630 A at 40 °C ambient, but it derates linearly as the panel temperature rises: 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. Maximum power loss is 162 W, which matters for ventilation planning in a sealed cabinet. The base unit is the 3VA2463-5JQ32-0AA0, so the switch deck is field-replaceable if the aux configuration needs to change later. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint for a 630 A frame. If you're swapping into an existing panel that was laid out for a different 630 A MCCB, check the busbar centers and the lug position — the 138 mm width is common but not universal.","metaTitle":"Siemens 3VA2463-5JQ32-0JL0 SENTRON MCCB, 630 A, 3-Pole, 187","metaDescription":"Siemens 3VA2463-5JQ32-0JL0 SENTRON molded case circuit breaker, 630 A, 3-pole, 187 kA breaking capacity at 240 VAC.
