If the breaker lives inside a hot enclosure near other heat sources, use the 60 °C or 65 °C column — 510 A or 480 A respectively — for the realistic continuous load. ## Integrated release and communication The basic switch variant is 3VA2463-5KP32-0AA0. No auxiliary switch or ground-fault monitoring is fitted on this variant. ## Panel fit — dimensions Dimensions: 248 mm height, 138 mm width, 110 mm depth. The width occupies three 45 mm pole pitches on a DIN-rail or mounting plate. Depth clears most 120 mm-deep enclosures; verify gland-plate clearance for the rear terminals. ## Power loss and temperature limits Maximum power loss is 162 W at rated current. The operating maximum of 70 °C matches the derating table endpoint — running at 70 °C ambient caps the continuous load at 450 A.","metaTitle":"Siemens 3VA2463-5KP32-0KA0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0KA0 molded case circuit breaker, 630 A rated at 40°C, 3-pole, 187 kA at 240 V.
