Three poles, rated insulation voltage 800 V, and a maximum power loss of 162 W that you'll need to account for in enclosure thermal calculations. The headline 630 A continuous rating at 40 °C is the starting point, but this breaker derates linearly as ambient temperature rises: 600 A at 45 °C, 570 A at 50 °C, all the way down to 450 A at 70 °C. The adjustable thermal-magnetic trip unit has a minimum setting of 945 A and a maximum of 5 670 A for short-circuit protection, with an initial value of 126 A for the thermal element. ## Communication and integration This MCCB includes a communication function, meaning it can report status and accept remote commands over a bus system — critical for a modern distribution panel where you want load shedding or remote trip indication.","metaTitle":"Siemens 3VA2463-8JQ32-0AA0 SENTRON MCCB, 630 A, 440 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-8JQ32-0AA0 molded case circuit breaker, 630 A continuous, 440 kA breaking at 240 V.
