The part sits in the 3VA2 series, which is Siemens' current-generation MCCB platform. That matters if you're stuffing this into a hot panel or near a motor drive; you don't lose half your capacity at the top of the ambient range. At 415 V it still holds 187 kA, and at 690 V it drops to 9 kA — that's the system voltage limit; above 500 V the fault current capability falls off fast, so coordinate the upstream transformer impedance accordingly. The adjustable trip range spans from 945 A minimum to 5 670 A maximum. That's a 6:1 ratio, which gives you room to dial in the instantaneous pickup for motor inrush or transformer magnetizing current without nuisance tripping. The 164.5 W maximum power loss is the heat it dumps into the enclosure — factor that into your panel cooling if you're running it near the top of its rating. At 110 mm deep, 138 mm wide, and 248 mm tall, this is a standard-size 630 A MCCB frame. It's meant for bolted connection to a busbar or cable lug set in a switchboard — no DIN rail mounting on a breaker this size. As a SENTRON product from Siemens, this breaker carries IEC 60947-2 and UL 489 certifications for molded case circuit breakers. The communication function supports integration into power monitoring systems via the 3VA communication module. No separate ground-fault monitoring version is included — that's an add-on accessory if you need GFCI functionality.","metaTitle":"Siemens 3VA2463-6KP32-0CA0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens 3VA2463-6KP32-0CA0 SENTRON molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, 242 kA at 240 V.
