Siemens 3VA2163-5HN32-0DC0 — 63 A SENTRON MCCB with Undervoltage Release
The Siemens 3VA2163-5HN32-0DC0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C through 70 °C — no derating needed across that ambient span. That interrupting rating means it clears a bolted fault up to 121 kA without rupturing, which covers most industrial service-entrance and distribution panel applications at 415 V. Show me the rating — this one holds. No exceptions on that safety function.
Interrupting Capacity Across Voltages
Breaking capacity varies sharply with system voltage: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V AC. At 415 V the 121 kA rating gives generous headroom for most industrial switchgear lineups.
Max power dissipation is 6.5 W; factor that into enclosure thermal rise calculations, especially in a sealed panel.
Environmental and Storage Limits
The storage range exceeds the operating range — handling and warehousing, not running, is what that limit governs.
