The 630 A full-scale value with an initial trip threshold of 126 A means it clears low-level overloads before they escalate — the trip curve starts engaging well below the frame rating. Breaking capacity drops predictably as voltage climbs: 75.6 kA at 500 V, and 9 kA at 690 V. That 690 V figure is the ceiling — above that, coordination with upstream devices becomes critical. The thermal derating curve is what you actually spec against in a closed panel: at 50 °C it carries 570 A, at 60 °C it's 510 A, and at 70 °C it drops to 450 A. Power loss hits 162 W maximum, so factor that into your ventilation budget. No undervoltage release is fitted, so if you need UV protection that's a separate add-on. The basic switch variant is 3VA2463-5JQ32-0AA0. The 138 mm width is a 3-pole frame. That storage minimum matters if this sits in an unheated warehouse before installation — it's fine down to -40 °C, but let it warm above -25 °C before closing the breaker under load.","metaTitle":"SENTRON 3VA2463-5JQ32-0JC0 MCCB, 630 A, 187 kA at 240 V","metaDescription":"SENTRON 3VA2463-5JQ32-0JC0 molded case circuit breaker, 630 A rated at 40 °C, 187 kA breaking at 240 V.
