The Siemens SENTRON 3VA2163-6HL32-0DC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full ambient range from -25 °C to 70 °C — no derating needed up to that ceiling. The adjustable thermal-magnetic trip unit covers a 95 A minimum to 756 A maximum, giving you a wide coordination window for downstream branch circuits. Interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V, so it handles high-fault utility feeds without cascading upstream.
Panel integration & footprint
The 63 A continuous rating at 40–70 °C means this breaker holds its full ampacity even in a warm panel — no derating curve to calculate. The adjustable trip range (95–756 A) lets you set the magnetic pickup to coordinate with downstream breakers or motor starters, avoiding nuisance trips on inrush while still clearing faults fast. The 242 kA SCCR at 240 V is typical for a high-capacity service entrance breaker; at 690 V the 3.7 kA rating reflects the reduced arc-quenching capability at that voltage, so verify the available fault current at the point of installation.
