Product details

The Siemens 3VA2463-8KQ42-0AA0 is a SENTRON molded case circuit breaker rated for 630 A continuous at 40 °C, with a 4-pole configuration and an ETU860 electronic trip unit. The 630 A rating governs the maximum uninterrupted current in a 40 °C ambient — push above 40 °C and it derates to 450 A at 70 °C, so panel placement and ventilation matter. Breaking capacity hits 440 kA at 240 V, 330 kA at 415/440 V, 220 kA at 500 V, and 52.5 kA at 690 V — that covers most industrial service-entrance and distribution fault levels without cascading upstream.

Communication function is built in — no external module required for basic connectivity. Optional motor drive available for remote switching.
