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.","metaTitle":"Siemens 3VA2163-5HN32-0DC0 SENTRON MCCB, 63 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA2163-5HN32-0DC0 SENTRON molded case circuit breaker, 63 A continuous, 3-pole, 121 kA breaking capacity at 415 V AC.
